The Kokko Booster mini guitar effects pedal has a sturdy construction and sounds just as good as some more expensive, big name pedals available on the market. It might not have the same range and configuration options but within the remit of what it's capable of, it can achieve similar effects to the premium pedals on the market.
It is one of the only boost pedal in this price range with bass and treble controls which is really nice because it allows you to dial exactly the amount of warmth and bite you want from your sound. Mixed with a compressor this pedal can do everything from mellow blues, to psychedelic, to the funkiest funk. As a straight booster to cut the mix on a solo it will do that in spades and the two tone knobs allow you to change your tone as much or as little as you want.
The one drawback to this pedal is that it offers quite a bit of boost even with the drive knob turned all the way down. Ideally, with the drive knob all the way down you should get no boost and then could dial in exactly the amount you wanted. This would make the pedal much more versatile, especially when coupled with an overdrive pedal to kick the drive from subtle to in your face.
The Kokko Booster is more than capable to be used as a main drive pedal providing great balance of crunch and tone. That's why we think it's an easy recommendation for those looking for a budget boost pedal.
