The Harmonious Monk Mk.2: Analog Tremolo with Tap, Ramp, and Vintage-to-Modern Versatility

All-Analog Tremolo with Expanded Creative Control

The Harmonious Monk Mk.2 takes JAM Pedals’ celebrated collaboration with That Pedal Show and pushes it even further, delivering lush harmonic and amplitude tremolo in a fully analog circuit. Retaining the rich, organic tone of the original, Mk.2 adds powerful new features that make it equally at home on guitar, keys, or virtually any source. From subtle, vintage sways to radical, choppy pulses, this is a tremolo built for players who want depth, character, and control.

Tap & Ramp Performance Features

The standout upgrade is the Tap & Ramp mode, letting you tap in your desired tremolo speed with precision, then ramp to a second, user-set speed for expressive dynamic shifts. You can even control how quickly the rate changes between the two speeds, opening up new rhythmic textures mid-performance. Prefer the original behavior? Legacy mode preserves the Mk.1 feel while adding selectable speed multiplication for instant double or dotted rhythms.

Three LFO Waveforms for Maximum Range

Mk.2 expands to three selectable LFO shapes in both harmonic and amplitude modes: smooth sine, punchy square, and edgy reverse sawtooth. Whether you want silky modulation, percussive chop, or angular retro vibes, you can dial in the perfect motion. The CHOP feature in square mode creates a dramatic kill-dry stutter for rhythmic, gated effects.

Dial In Your Perfect Tremolo Texture

Front-panel controls for depth, speed, level, and dry/effect mix let you sculpt the effect to fit seamlessly into your tone. Internal trimmers for bass, mids, and treble EQ, plus an input gain adjustment, offer fine-tuning to match different instruments and rigs. True bypass switching keeps your dry signal pristine, and the all-analog design ensures warm, natural movement.

Built for Stage and Studio

Compact, rugged, and thoughtfully laid out, the Harmonious Monk Mk.2 is a versatile creative tool for players who demand both tone and flexibility. Whether you’re after subtle vintage shimmer or complex modern rhythmic modulation, it delivers with ease.
