Up for sale is a JAM Pedals Harmonious Monk Mk.2 Tremolo, presented here in excellent condition and fully functional throughout. Built in Greece with the unmistakable hand-painted aesthetic JAM Pedals are known for, this is a premium, all-analogue tremolo that goes far beyond the standard pulse-and-throb territory and into genuinely inspiring modulation.

The Harmonious Monk Mk.2 is the result of a collaboration with That Pedal Show, and it shows in the sheer musicality of the design. At its core, you’re getting both harmonic and amplitude tremolo modes, each with distinct character and feel. Harmonic tremolo delivers that elusive, phase-like swirl associated with early 1960s American amps, while the amplitude mode covers everything from subtle vintage shimmer to hard, choppy stutter. With two selectable LFOs and a wide gain range, the pedal effectively offers four core voices, all of which can be dialled in with impressive precision.

The Mk.2 version expands on the original with highly usable modern features, including tap tempo and a ramp function that allows you to transition between two speeds on the fly. This makes it incredibly expressive in a live setting, whether you’re adding movement to clean passages or creating dramatic rhythmic shifts mid-song. A legacy mode is also included, offering rhythmic subdivisions for even more flexibility, alongside additional waveform options and internal controls for fine-tuning the pedal to your rig.

Sonically, this is one of the most immersive tremolo pedals available. It can sit subtly in the background, adding width and dimension, or take centre stage with rich, undulating textures that blur the line between tremolo, vibe and phaser. The mix and depth controls make it easy to integrate into any setup, from traditional mono rigs to more complex wet/dry configurations.

Condition-wise, this example has been very well looked after, showing only minimal signs of use consistent with careful ownership. All controls operate smoothly, the footswitches are solid and responsive, and the pedal performs exactly as it should. It will ship safely packaged and is ready to drop straight onto your board.

If you’re looking for a tremolo that combines vintage character with modern flexibility, the Harmonious Monk Mk.2 is about as good as it gets, equally at home delivering subtle movement or full-on hypnotic modulation.
