In the words of JAM Pedals:

We have a deep love for the harmonic tremolos unique modulation character: a little bit phase-y and a little bit pulsing. It can add a complete, enveloping texture over your whole guitar tone, or sit more subtly as a fantastic widening effect either straight mono or in a wet/dry rig.

We wanted to address some of the issues we found in our other favourite examples of the effect and add a superb amplitude trem to boot; enter the Harmonious Monk, a collaboration between JAM pedals and That Pedal Show!
