JAM Pedals Harmonious Monk mk2

Jam Pedals · pedal

The JAM Pedals Harmonious Monk MK2 significantly expands on the original MK1 harmonic tremolo circuit, adding Tap Tempo for matching rate to song tempo and a Ramp function that lets players hold the Tap switch to smoothly glide between two programmed speeds. It adds a third selectable LFO waveshape (sine, square, and reverse sawtooth, versus the MK1's two), a Legacy mode preserving the original MK1 character with an added x2/x1.5 speed multiplier for dotted-eighth pulses, and a fourth internal trimmer specifically for optimizing input gain across guitar, bass, keys, or other instruments.
