JAM Pedals Harmonious Monk mk.2

Building on JAM Pedals’ award-winning collaboration with "That Pedal Show" the mk.2 retains the original’s all-analogue circuitry and modern-classic tone, but adds features to make it even more useful and functional on guitar, keys and anything else!

The headline new feature is Tap & Ramp mode. You can now tap the time of your
tremolo using the second switch, but a longer press will ramp to a second speed that can be set anywhere you like. You can also set the rate of the ramp between the two tremolo speeds.

There are now three selectable LFOs (instead of two) providing varying shapes of modulation in both Harmonic and Amplitude modes: sine wave, square you can dial in everything from subtle, vintage-inspired tremolos all the way to otherworldly staccato choppiness! 

Mk.2 also has a Legacy mode, so everything you know about mk.1 can remain intact if you prefer it that way…  with an additional option on the rate of the second, preset speed. Depth and mix controls enable you to set the effect intensity to sit perfectly in
your tone, and should you wish to tweak further, there are internal trimmers for bass, midrange and treble EQ on the effected signal. We have added an input gain control to optimize Harmonious Monk mk.2 in environments other than a traditional guitar rig.
Harmonious Monk mk.1 remains a truly awesome and inspiring tool. Mk.2 spreads some features icing on an already incredible sonic cake.
