Jam Pedals · pedal
The JAM Pedals Harmonious Monk MK1 is a harmonic tremolo pedal, the original version in the line, offering two selectable LFO waveshapes and three internal EQ trimmers for tonal adjustment. As the first-generation circuit, it predates the MK2's added Tap Tempo, Ramp function, third waveshape option, and dedicated input-gain trimmer, delivering the foundational harmonic tremolo character the series is built on, though some players noted it could subtly color the guitar's base tone by boosting certain frequencies.
