Harmonious Monk MK1

HARMONIC & AMPLITUDE TREMOLO

Used only in studio smoke free environment.

The JAM Pedals Harmonious Monk Mk.1 is an all-analog harmonic and amplitude tremolo pedal designed in collaboration with That Pedal Show (Dan and Mick).

Key Features & Controls

• Four Core Sounds: Combines two selectable LFO intensities (Subtle/Vintage vs. Intense/Chop) with two modes—Harmonic tremolo (phase-like, shifting modulation) and Amplitude tremolo (classic volume modulation).
• External Controls:
• • Depth (D) & Speed (S)
  • Level (L): Master volume that can boost or cut the signal above or below unity gain to fix perceived volume drop.
  • Mix (M): Wet/dry blend control for fine-tuning effect intensity.
  • Harmonic / Amplitude (H/A) toggle switch.
  • Subtle (-) / Intense (+) toggle switch.

• Footswitches: On/Off true-bypass switch and a left-hand Double-Speed switch (allowing you to double or halve your active speed).
• Internal Trimmers: Three internal trim pots for 3-band EQ (Treble, Middle, Bass) affecting the wet signal to dial in tone match with your amplifier or dirt pedals.
