As you can see, Harmonic Square have a novel design logo, classic mini size, convenient and durable. True bypass switch lets your instrument’s signal pass through a non-electronic bypass line when the effect is disengaged, feeding your amp with direct, unaltered signal from your instrument
The pedal can change the pitch of a note by 2, 3, 4, 5, 7, 12 or 24 half-steps up or down. It can also detune by increments of partial steps. Separate pots allow blending of the processed (wet) and unprocessed (dry) signals. The build quality is excellent, made of metal with a nice finish. The different sounds the pedal is capable of achieving are hugely impressive. It really does sound like an organ at times.
Overall it's another solid and great value pedal from Donner. Check it out for yourself!
