More than just a vocal effects pedal, infact the Boss VE-8 Acoustic Singer is an all-in-one effects and preamp provider for acoustic guitars and vocals. It’s not a secret that Boss has a strong reputation when discussing and comparing guitar effects pedals. Their VE-8 Acoustic Singer is certainly a contender for most versatile harmonizers on the market at this moment. If you’re in the market for a pedal that’s a bit more complex than the usual stuff, this vocal harmonizer pedal should have your full attention.

It starts off with dedicated preamps for instrument and mic, both of which come with completely independent effects, of which the microphone side component stands out due to it’s myriad of features. This includes fundamental effects like smart harmony and reverb, while also including developmental effects such as distortion, robot and more electronic effect types.

When Boss set out to make VE-8, they didn’t just want to build a solid vocal harmonizer. They went a bit further than that. VE-8 features a wide double stack body that brings a lot of that classic Boss reliability. It’s rock solid and inspires enough confidence to be used on just about any stage out there.

The top panel is where all the major controls can be found, and they are not short on numbers. Boss VE-8 packs a very impressive vocal harmonizer effect along with a looper and a chorus. Additionally there is a reverb available for both the guitar channel and vocals channel. In terms of I/O options, you’re given the standard microphone and instrument lines with optional Phantom Power, not forgetting stereo modes. Boss included a USB port, allowing users to connect VE-8 to a laptop/computer. Controls might seem confusing, but after a little while, they become very intuitive. The control interface is split into four areas. At the top, you have the instrument cluster, vocals cluster, and standard output section. In the lower area of the pedal you’ll find the foot switches. Depending on how you press them, these switches will initiate memory mode, or activate the on board tuner.

While focusing on the guitar element of the pedal we find it’s just as packed, with built in effects, such as delay and an interesting acoustic resonance that enhances the sound of piezo equipped acoustic-electric guitars. It’s an amazing all-in-one vocal harmonizer pedal, and it’s recommended for both traditional and adventurous singer-guitarists.

When it comes to ‘End Product’ , Boss VE-8 is a real powerhouse. What is most interesting is the quality of the available effects. Often times when you get a ‘jack of all trades’ type pedal like this one, it is usually strong in some areas, but mediocre in others. VE-8 doesn’t have that issue. On the contrary, the sound is very natural, especially when used as intended with acoustic instruments. Having 50 different Memory slots also helps a lot. You can basically dial in a setting you want, save it, and pull it out of the library later on.

While it gets most of the thumbs up from its quality mic harmonies and reverb, it also impressed many of guitarists. There are a few who were not satisfied with some of the extra effects, but still loved the Boss VE-8 overall. Boss VE-8 pretty much nails what every acoustic guitarist needs while up on stage. The features alone make this a great tool to have available in any studio or on any stage . To summarize, it’s one of the best vocal harmonizer all-in-one pedals you can get on the market today.

The likes of DigiTech and TC Helicon have professional vocal processors that are aimed at singer/guitarists, and now Boss has got in on the act with the new VE-2, which can take an input from your electric guitar to control your harmonies – something that wasn’t available with its previous VE-20 and VE-5 models. Now, Boss is a company that needs no introductions when it comes to vocal harmonizer pedals, vocal effects pedals or general music equipment. They’re famous for creating high-quality music equipment, which are designed and built to last for a lifetime.

Although Boss is under pressure by brands like TC Helicon when it comes to harmonizers, they are still holding their ground. Boss VE-2 is a cost-effective, simple, but also one of the most agile vocal harmonizer pedals out there. Let’s take an in depth look and see what it’s really made of.

The VE-2 offers 12 different harmony types to add to your own voice, each featuring one or two voices above and/or below it, plus a switchable variation option with more voices for richer harmonies. The pedal also comes with several vocal improvments such as delay, reverb and compression with or without frequency correction. We personally think that the Boss ve-2 sounds fantastic, particularly if you use it subtly, lowering the balance knob settings, so that it accompanies the main vocal, but doesn’t drown it out.

Right from the start, it’s perfectly clear the VE-2 is a vocal harmonizer pedal and not much more. Boss has other models which are far more dynamic and multi functional, but this one was designed to deliver the core of this effect. Even so, they did include basic reverb and delay effects. You can’t modify them too much, nor are there many types to select from. You can simply select either one, or mix the two of them. That being said, the quality of the pedals build is on that standard, somewhat expected Boss level.

The Boss VE-2 also has an interesting function, called ‘Auto Harmonist’… This is fantastic for singers who want to connect an instrument to the VE-2 such as a guitar, as the unit senses and detects the chord progressions used, to work out the musical key that the vocals should follow… Absolutely fantastic if you have key changes in the song, as this unit is able to listen to the change in chords (mid-song) and then adapt the harmonies accordingly.

For all the troubles of navigating the crowded control interface, your reward is a very solid core performance. We are talking pretty organic tone even when you go crazy with harmony modes. Built in delay and reverb are okay, but nothing to write home about. With that said, they won’t stand out as artificial if used lightly. When it comes to tracking, things are great.

The unit’s ‘Enhance’ component gives the singers immediate access to dynamic and subtle frequency correction at a touch of a button. The button specifically adds compression and analyses the vocal tone to automatically filter certain frequencies and boost others, helping to give a more refined, studio-quality sound.

The vocal harmonizer pedal has little trouble following you through complex chord progressions. Dropping it into hybrid mode yields some fairly interesting results. Depending on your settings, having that manually set key can help a lot. What matters the absolute most is that the vocal pedal tracks perfectly fine even in this mode. In essence, Boss VE-2 is everything it claims to be. Nothing more and nothing less. That is something we can appreciate.

Overall, we really like the Boss VE-2 unit. As we mentioned, not only does it provide a simple to understand interface with easy-to-use controls, but its delay, harmony and reverb effects actually sound pretty good. At the end of the day, Boss VE-2 represents a fairly affordable alternative to more complex designs out there. It’s simple, offers rock solid performance as well as reliability. We’d love to see a better organized control panel, but that is not too big of a deal all things considered.

Not only does the unit sound good, but it provides a good amount of variety for singers to play around with and find their favourite sounding tones and configuration combinations, which can be saved and referenced instantly simply by utilising the unit’s 3 preset memory banks. As far as who the VE-2 is ideal for, Boss have made a great decision in not only providing interface controls to control the musical key settings, but also in providing the auto harmony function for singer/songwriters who want to plug in their instruments instead.

The VoiceLive Play Acoustic is an extremely valuable and versatile tool for the singer/songwriter (acoustic guitar player and vocalist). It allows you to send a refined vocal and acoustic signal to your sound technician. TC Helicon offers a number of specialized harmonizer solutions. One for example comes in the form of the ‘Play Acoustic’ processor. Not only is particularly good, but it is certainly one of the most versatile vocal harmonizer pedals on the market.

Focusing on the vocals, you can make use of the vocal effects. Play Acoustic brings so many features that it’s hard to cover them all. To start with, let’s clarify that there are two different types of effects encapsulated in this device . Guitar effects and vocal effects. Vocals section comes with Adaptive Tone technology. In essence, this feature automatically EQs your voice, adds compression if necessary and de-esses mic channel. Then we have couple of types of reverb, delay, harmonizer and hardtune to name but a few.

Controls on this pedal are kept nice and simple. For a unit that offers so much, it is impressively easy to use. The center of the top panel is dominated by a large display, with a number of buttons located by it. Many of these buttons are used to navigate around the user interface and to select different features. A great thing about this setup, aside from its digital format, is the fact that everything is illuminated. You can still navigate the pedal easily even when in the darkconditions. For the harmonies, you’ll need to play with the different options to find the harmony effect you need for a particular song. You can also set the key for the song, or let the pedal determine the key from your acoustic guitar input. I personally found auto works well most of the time, but I had better results when I set the key for the harmonies.

The VoiceLive Play Acoustic comes with a number of additional features that are quite useful. You can use it as a looper, and you’ve got a tuner onboard as well. Personally I enjoyed using the reverb and BodyRez effects. The BodyRez is also available as a stand-alone pedal. It really does add a nice resonance and body to your instrument on both the bottom and top end of the EQ spectrum. I found it easy to dial in a sound (you get a lot of parameters) for my specific acoustic guitar, and it really did make a big difference in the sound.

It’s no secret that we had high expectations in regards to this pedal’s performance. After playing with a few of their other models, TC Helicon has really grown on us, especially in the harmonizer segment. Unsurprisingly, Play Acoustic met and exceeded all of our expectations. One thing we were most concerned about was that auto equalizing mode for vocals. That simply sounded like something that just wouldn’t work right. We were proven wrong. As weird as it is, the Adaptive Tone technology was actually pretty accurate with compensating for different vocal profiles.

You can change the mic input gain as well as the mic input type. Input/output settings are extensive and flexible. I would recommend visiting the TC Helicon link above and taking a look at the manual to see everything this pedal is capable of.

At the end of the day, our time with TC Helicon Play Acoustic was great. The pedal was very responsive, quick on its feet and followed input with clinical accuracy. While there are definitely cheaper models on the market, this one is absolutely worth every penny you invest in it.

If you’re an instrument player, you’ve probably heard of the company TC Electronics, as they are quite famous for their high-end guitar effect pedals like looper and overdrive pedals. TC Helicon, their subsidiary, seems to follow this tradition with some excellent vocal processors and some of the best vocal harmonizer pedal (spoiler alert: this isn’t their only product on my list).

The Harmony Singer is a compact harmony pedal that is highly rated. It is similar to the Harmony-G XT, but stripped down of extra features in favor of portability. It carries the same smart harmony effect that follows after guitar chord changes, but in a smaller foot print that is easier to carry and setup. It is simply the practical choice for singing guitarists who are looking to add harmonies without having to audition actual singers or carry bulky equipment.

TC-Helicon is probably one of the most popular brands when it comes to harmonizers. It’s not hard to see why when you take a look at Harmony Singer. This pedal features a compact yet a rigid body that can withstand use on and off the stage with ease. The top of the vocal pedal is where all of your controls are at, however, the front and either side is where you will find all the I/O ports.Right and left panels feature the instrument input and thru ports.

What’s awesome about TC Helicon Harmony Singer would have to be how intuitive the controls are. You will see three aligned knobs on the top panel which include Harmony, Level, and lastly Reverb. Harmony knob allows you to decide between four different types of voices, all featuring far and close setting. The range of the harmonizer effect is two voices above or below the input signal, with all of the other combinations available. When it comes to the Reverb feature, you’ve got four different options for this effect.

The pedal listens the chords you play and tracks your guitar, maintaining a perfect pitch. It’s simple to connect and set up, although it’s best if you keep it at the front of the chain if you have multiple pedals.

When the time comes to plug this vocal harmonizer pedal into your rig to give it a spin, you’ll pleasantly surprised by the resulting sounds. The first thing that catches your attention is the tone. It doesn’t present as being robotic like some other vocal harmonizers do, and it actually has a softness to it. The Close mode is a bit aggressive and in your face, but there are definitely applications where it works. The Far mode is a lot more subtle but still every bit as efficient.

At the end of the day, TC Helicon has created yet another great package for those who need little more girth in their music. The pedal works well, is very accurate and most importantly, simple to use. There are some quirks, but those are far from being a deal breaker.

Once upon a time there was a vocal processor from Boss called the VT1 and it provided a convenient toolset of voice effects, from gender reassignment to Metal Mickey robotics. By performing its few tasks well and with minimum fuss, it gained something of a cult following. Joining Roland’s Aira range as the junior member is the VT4, an updated version of the VT1, but built for the same instant gratification as its predecessor.

Roland’s BOSS VT-1 Voice Transformer has been used on hit tunes and albums by major acts including The Knife and Air. The VT-4 is unmistakably an AIRA product. It has the same solid build quality, sleek looks, green lights, brushed black aluminium front panel, black plastic case and green day-glo trim as its TR-8 and TB-3 siblings and it’s also very compact too.

The VT-4 doesn’t stray far from the VT-1’s concept in terms of functionality and the hardware itself – in fact it’s strikingly similar if you compare the two, though thankfully the garish orange and blue colour scheme has departed!

Plug and play is the order of the day and having connected my AKG D130 mic, it was just a case of adjusting the sensitivity of the input, keeping a wary eye on the peak LED, then letting rip. The central encoder’s 10 positions each select a different processing algorithm and just three user memories are provided to store your favourite combinations of the front panel controls. This is considerably less generous than the VT1 and since one potential role for the VT4 is for voice‑over work, more memories would have been much appreciated. Fortunately, the VT4 is very hands‑on so this limitation may not prove too irksome.

If you have a spare sustain pedal it can be used to toggle the bypass status, and in one of only a handful of configuration options, you can change its polarity to suit the type of pedal you have. Finally, if you don’t look carefully, you might miss the mini‑jack headphone socket and additional mic input under the panel at the front. Using the pitch and formant levers together generates a wide variety of pretty transparent vocal modifications. It’s never been easier to morph from Barry White to Barry Gibb! Certainly the results are cleaner than earlier Roland technology, such as Variphrase, and with the robot button always handy, Direct might be all the processing you ever need.

The next two options are Auto Pitch 1 & 2. Described as pitch‑correction, their attempts at following the frequency of my incoming voice were met with mixed success. Admittedly, it’s been many decades since I was in my vocal prime and time hasn’t been kind to my vocal cords. When I trotted out a rusty bit of Palestrina, the VT3 struggled to identify the pitch, let alone follow it reliably. In contrast, I plugged in my theremin instead of the mic and, perhaps due to the consistency of delivery and tone, the process worked far more reliably.

Auto Pitch 2 is instantly more artificial, its electronic artifacts not unlike those of Variphrase. As my latin motet renditions slipped effortlessly into Cher (not a phrase I thought I’d ever need), the blatant Auto‑Tune character became more unruly than ever. Auto Pitch 2’s response to vibrato was to glitch wildly and I never fully gained control over the tuning. I suspect that to get the best out of either of these modes, you need a voice that’s already pretty good and I got my most interesting output by abandoning the voice altogether and using other sources, such as a drum machine.

In use, the VT-4 is great fun just like the old VT-1 and in particular, the new Synth, Bass and Lead modes (that turn your voice into a synth, bass or lead sound) are great for anyone who wants to record or perform synth lines but that can’t play a keyboard. Then there’s the Scatter effect which is great for real-time chopping and twisting of audio and beats, plus the onboard reverb sounds great on all sources, though it’s a shame you can’t alter the time, size or type. The VT-4 is in its element when you start pitching up or down beats/instruments and samples or when you want to harmonize with yourself, plus the effects such as Radio and Megaphone though clichéd, are handy to have on tap.

To sum up, the VT-4 is a mixed bag. It’s certainly fun messing with your voice, it’s a great box for voice-over artists and the built-in USB Audio interface is a real bonus. However, for pitch-challenged singers (like us), the Autopitch and Vocoder presets are a little disappointing compared to the competition. This is an easy one to sum up: the VT4 is much prettier than the VT1 and considering its price, accessibility and bundled audio interface. I predict this is one of the best vocal harmonizer pedals available and will make a lot of vocalists very happy.

The TC Helicon Perform VK is the ideal vocal processor for pianists and keyboard players, with this device having a range of functionality; TC Helicon has really created an effects pedal that can be used both in live performances and studio recordings, with the sheer quality of internal hardware. The interface is incredibly simple to use, and the device can be used with a 3 button, or 6 button foot pedal to allow for ease of switching between effects during a performance.

PERFORM-VK combines studio-grade vocal effects with convenient stereo keyboard I/O, providing an unparalleled live performance experience for you and your audience. And thanks to built-in, multi-channel USB audio, you’ve also got a full recording interface right at your fingertips.

The keyboard integration means that Perform-VK can ‘listen’ to the chords played on keys and use them to intelligently determine harmonies. But even if you don’t have a keyboard on hand, the built-in RoomSense mic lets you practice without a mic and automatically controls harmony. Perform-VK is also compatible with remote mic control and with optional foot switching through the company’s MP-75 or MP-76 microphones or Sennheiser’s e835 FX mic and Switch-3 or Switch-6 footswitches. There’s also a multitrack four-in, eight-out USB audio interface option through which you can easily record your creations.

Those who will benefit from this the most are musicians in small bands who take care of their own sound. However it’s also a great tool for any band with a keyboard player and a shortage of sound engineers or backing vocalists. The TC Helicon Play Acoustic is the ideal all-in-one effects processor for singer/songwriters who play the acoustic guitar and want an effects pedal which integrates vocals and acoustic guitar. This device is a premium-grade vocal and guitar processor, and as you can hear from the demonstrations, offers superior sound quality.

Many companies have a kind of tiered approach to their pedals. Boss does not just offer the RC-300, for example, they put out the RC-3 and RC-30 too, which package basically the same core features into different-sized units, with some of the capability shaved off as you get smaller and smaller. It ain’t easy being a singing guitar player, but TC-Helicon’s new VoiceLive 3 aims to make your switching and effects easy by combining vocal and guitar processors, as well as a looper, into one ingenious package.

It may seem like I have a thing for TC Helicon, but trust me – when searching for the best vocal harmonizer pedals, you’ll be stumbling across many of their products. This Canadian company devoted itself to making professional, high quality vocal processors. There are many ways you can use the unit, thanks to the wealth of connections on its rear panel, but your basic guitar/ mic setup sends vocals via an XLR output to a PA, and guitar signal from a jack output to your amp – the signals are kept separate, so you won’t get vocal harmonies blaring through your guitar rig.

At first glance, the VoiceLive 3 Extreme looks like the original VoiceLive but with a slightly cooler makeover. The soft silver of the standard edition has been replaced by a solid black, and the upper portion has a kind tattoo-like decal in the background. The Extreme version offers more than these purely cosmetic changes – which are genuinely pretty good – but you’d be forgiven for thinking it’s just more of the same.

The VoiceLive 3 operates using presets – there are 250 factory patches, with plenty more slots to store your own edits, but you can switch effects in and out within a preset. Two footswitches scroll up and down through the presets list, but you also get an extremely useful Step footswitch, which lets you step through different seems in order – the idea being you can store different sounds within one preset for different song sections. With plenty of built-in options and great-sounding effects, this is the most advanced pedal on the list, but it comes at a significant increase in price, as well as complexity.

The effects are high quality, and the harmonies track your voice well – assuming you can sing in tune in the first place. Harmonies can be set to a fixed scale but – and here’s the good bit – they can also be set to automatically change with your guitar chords. The classy-sounding guitar effects are derived from sister company TC Electronic’s TonePrint pedals, and there’s a complete pedalboard’s worth that can be switched individually or collectively. You also get amp simulation in the signal chain, featuring a range of amps.

    The Voice Box, at it’s heart, has a 256-band vocoder, which is impressive as it means a clear diction. To emphasis this, the microKorg has an eight-band vocoder. The Voice Box has six harmony/two octave modes for accompanying solo singers.

    Electro-Harmonix is a well-known brand of effects pedals. As such, their approach can often times be different. Electro-Harmonix’s Voice Box Harmony Machine definitely follows one of their more unusual designs, but also one of the most reliable and best vocal harmonizer pedals you can get right now. Let’s check out this bad boy.

    Well known for their extensive line of quality guitar pedals, EHX knows that there’s always room for one more pedal. So with the Voice Box, they decided to create a pedal for singing instrumentalists to play with, resulting in a vocal effect pedal that can handle harmony and vocoder duties in one package.

    First up is the Blend dial that controls the balance between your dry/effected voice. Next are two Reverb dials (dry/harmony). The reverb, while fairly dark sounding, is very useful. You could have a dry vocal with reverbed harmony effect for example, or vice versa.

    If you have seen one Electro-Harmonix pedal, you have pretty much seen them all. Aside from the graphic design on the top, not a whole lot of stuff changes. We still have the main row of knobs at the very top of the pedal, while the foot switches are at the bottom. In the middle of its interface, you will find LED diodes which indicate the harmony mode you’re in. Knobs include Blend, Dry and Harmony knobs for Reverb, Gender Bend, Voice Mix and Preset Select knob.

    You can switch between nine harmony modes that cover quite a lot of ground, from low to high, to multi-harmonies and octaves. Its coolest feature however is the Vocoder mode which turns this professional vocal effect into a fun experimental effect. Other features include reverb and gender bending via pitch shifting.

    We found the harmony generation a little unstable and inconsistent at times, though useable results are possible after plenty of practice. While we can’t complain at all about the generated tones, the box would often have difficulty picking up any of the quick major to minor changes and some of the more jazzy inflections. Even though it does not come with cool LCD displays and similar flashy features, Electro-Harmonix Voice Box Harmony Machine is truly a force to be reckoned with. Better than that, it is just fun to use. Those who own a whole lot of different equipment could benefit from a unit such as this one.

    If you have seen one Electro-Harmonix pedal, you have pretty much seen them all. Aside from the graphic design on the top, not a whole lot of stuff changes.

In the middle of its interface, you will find LED diodes which indicate the harmony mode you’re in. Knobs include Blend, Dry and Harmony knobs for Reverb, Gender Bend, Voice Mix and Preset Select knob.

    At the end of the day, Electro-Harmonix has given us a fairly simple, yet straight to the point harmonizer. It’s very strong in places that matter, although some would probably write off points for the lack of advanced features. We’ve found it to be just the right kind of spicy. All in all, this is a fantastic vocoder and a very capable but sometimes frustrating harmony generation box. The harmony processor is very much reliant on very in-tune singing and decent vocal/instrument levels going in (ideally, use a compressor between the mic and the voice box).

    There was time when it was only guitarists who used stompboxes, but lately vocalists have been getting in on the act with specialised pedals that can generate harmonies, add reverb and even correct their out of tune warblings. TC Helicon’s pedals always go above and beyond. One look at TC Helicon’s VoiceTone Harmony-G XT proves that. Speaking of VoiceTone, it’s one of the best vocal harmonizer pedals you can get right now. Today we’re going to take a closer look and show you what it has to offer.

    This could be considered the little brother of the VoiceLive Play GTX, as they both use the same harmony algorithm. Great, automatic vocal tone-shaping, with five different settings. The doubling on this unit is VERY nice; very human-like.

    The very core of VoiceTone Harmony-G XT is the all new TC Helicon processor. It is the best they have to offer, and it is every bit as good as you would expect. The pedal is a double wide design that features a rugged body and great build quality. When you pick it up, it has some weight to it which definitely inspires confidence. The layout of controls and inputs is simple and to the point.

    The Harmony-G XT is the successor to TC-Helicon’s Harmony-G vocal effect and takes some features from the more upmarket VoiceLive 2. It’s designed to provide a variety of effects to enhance any singing performance including, among others, harmony generation, doubling effects, reverb, delay, compression and automatic chromatic frequency correction.

    It always amazes us how TC Helicon makes their controls simple to work with. Instead of layering multiple rows of knobs, they pretty much-reduced everything to the bare minimum. Top of the interface features four knobs. There’s Input level knob, Guitar, FX, and Harmony. Underneath those, there is a number of stealthy buttons which don’t stand out all that much. These are used to select presets, store presets, chooseeffects and more.

    Operation of the Harmony-G XT revolves around 10 programmable presets arranged in five banks as variations A and B. You can step through the banks with the preset button and switch between the A or B variations with the left footswitch. Each preset can be built up from several elements.

    Even though it’s pretty cool to look at, TC Helicon’s VoiceTone Harmony-G XT is even more interesting when actually used. Being a guitar controlled harmonizer with a fairly powerful processor, we were interested to see how well it tracks and anticipates changes in the melody. Needless to say, its performance was stellar in this regard. Not only can you feel trust in the pedal to do its job, but you don’t even have to hook in a microphone for it to work. The idea is that you play your guitar to generate vocal harmonies, although there’s also manual selection of scale and key for singers without an instrument or horn players. You can also use a guitar to manually set a key by playing a chord and holding both footswitches down.

    TC Helicon did a great job with this pedal. It might not have the fancy features like some other pedals do, but it covers the core stuff flawlessly. If you’re looking for a no nonsense harmonizer that packs a little extra flavor, this is the one to pay attention to. This pedal offers creative possibilities for vocalists and may be particularly suited to solo acts that want to add a little interest to their music or just present a bigger sound to their audience. Bear in mind, though, that this type of pedal demands to be used with caution, vocal pitchshifting technology isn’t without odd-sounding artefacts and a shift of just a few semitones can appear unnatural if mixed too high in relation to the main vocal.
