Harmonic Tremolo with a few twists!

The JAM team, along with Dan and Mick from That Pedal Show, set out to design the perfect Harmonic Tremolo.

Enter the Harmonious Monk, an all-analog tremolo pedal with both Amplitude and Harmonic modes.

Two selectable LFOs are also available for varying levels of intensity. Plenty of tweaking fun to be had here!

Harmonic tremolo is beloved for its unique modulation character: a little bit phase-y and a little bit pulsing.

It can add a complete, enveloping texture over your whole guitar tone (or sit more subtly as a fantastic widening effect)!

The Subtle setting on the pedal's Amplitude mode offers a plethora of vintage-inspired tremolo tones.

The Intense setting brings the chop: stuttering, staccato pulses that add drama and rhythm to your music!

Depth and Mix controls were added, allowing you to perfectly dial in the tremolo into your signal.

A footswitch gives you access to two tremolo speeds instantly and internal trimmers let you shape the EQ to your liking.

The Harmonious Monk covers a huge amount of sonic ground and it will inspire you towards a new palette of sounds and textures.


What’s new on the mk.2 version?

1. Tap tempo.

2. Ramp function: holding the Tap switch will ramp to a second speed.

3. A second mode of operation (Legacy mode) retains and expands on the mk1’s functionality.

4. New LFO waveform added (Reverse Sawtooth).

5. Kill Dry function.

6. New internal trimmer adjusts input gain to optimise the pedal for use with any instrument you might want to throw at it!

7. You can now specify the startup state of the mk.2, to ON or OFF upon receiving power!

Craig Estrela
Harmonious! This is the real deal.

Harmonious Monk V2 exceeded my expectations. There are so many great tones in this pedal. I was happy with the tremolos in my Strymon Flint V2, but after using the Monk V2, the Flint came off the board. Both great pedals, but the Monk for me is just more capable for what I want a tremolo pedal to do and it also sounds better. Analog vs digital. From
amazing smooth harmonic tremolo all the way to chop, it has tap tempo, double ramp up speed, and the legacy settings of V1. It can also do Uni-vibe tones. You won’t be disappointed if you get one of these. I’ve been shopping from Electric Mojo for a few years now and every time it has been an easy transaction, quick shipping, and products always arrive in excellent condition. If you are interested in this pedal or anything else from Electric Mojo and are on the fence, just reach out to their customer service. Charles is great.

Shipping was fast.

Yes, I just live the next province over, but I received this pedal the next day after I ordered it. The pedal arrived in new condition (packaged well). Great service!

The pedal itself is amazing. I love the double speed control.

My first tremolo

I’ve never had a tremolo before, but I did have a clunky univibe that I sold. I could do 2 for 1 with this Harmonious Monk pedal! It got me inspired to write new kind of music right at the first play. I strongly recommend it.
