JAM Pedals Harmonious Monk Tremolo Mk.2 Mk 2

As the name suggests this playful box is an updated version of original Harmonious monk, and a deep dive into the world of harmonic tremolo. The Mk.2 retains the features of the original version and notably adds tap tempo, a third LFO waveform, a kill/dry function, and an internal input gain trimmer to optimize for guitar, bass or keyboard. As with all JAM pedals, it's 100% warm organic analog tone, and hand painted in Athens, Greece. 

What is Harmonic Tremolo? Most players are familiar with Amplitude Tremolo, which is a volume-based roller coaster induced by deep volume swells, triggered by varying the amplitude of the waveform. This is true, tube-biased tremolo most notably present in the Blackface Fender amps. What most people don't know is that Fender also pioneered the unique Harmonic Tremolo in the short lived Brownface era. This technique uses a filter on the sound wave to separate the high and low signal and modulates the rest of the frequencies in the opposite direction. So instead of a simple swell, harmonic tremolo produces an ethereal swirling akin to a rotary speaker or old school vibe effect. To us it's a bit more inspiring than the tube bias effect, and lends itself to expanding genres and playing styles. 

We love our Monks, and it's a great tool for both recording and live performances. If you already have a Monk, you may not feel the need to upgrade. But if you don't have a Harmonious Monk, it's an indispensable tool for creating anything from subtle shimmering space to wobbly rotary psychedelia. Hot tip: If you turn the mix to 100% dry, it's also an excellent preamp boost. 


In the words of JAM themselves: 

What's new in version 2?
    1. TAP tempo

    2. Ramp function: holding the TAP switch will ramp to a second speed. You can determine the second speed, as well as the rate of the ramp between the two tremolo speeds.

    1. There is a second mode of operation called the Legacy mode which retains and expands on the mk.1’s functionality since now you can choose to have x2 (double) or x1.5 (dotted eighth) speed multiplying options!

    2. New LFO waveform added: Reverse Sawtooth

    3. CHOP (kill dry) function

    4. In addition to the mk.1's 3 internal EQ trimmers, the mk.2 features a new internal trimmer to adjust input gain control to optimise Harmonious Monk mk.2 for use with guitar, bass, keys, or anything else you might want to throw at it!

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


OPERATION MODE SELECTION:
The mk.2 comes with the Tap & Ramp mode preselected.
In order to switch between the Tap & Ramp and Legacy modes, keep both footswitches pressed until the LEDs blink, indicating mode change.


RAMPING FEATURE:
Only available while in the Tap & Ramp mode.
A prolonged press of the TAP footswitch will engage ramping from the original to the fixed user-selectable speed.
In order to determine the fixed user-selectable speed, while keeping the TAP footswitch pressed, adjust the Speed potentiometer to taste - make sure to return the Speed to the original position after releasing the TAP footswitch.
In order to determine how long it takes to travel from the original speed to the fixed user-selectable speed, while keeping the TAP footswitch pressed, adjust the Depth potentiometer to taste - make sure to return the Depth to the original position after releasing the TAP footswitch.


SPEED MULTIPLYING FEATURE:
Only available while in the Legacy mode.
An instantaneous press of the TAP footswitch will engage and disengage the speed multiplying function.
There are 2 available factors: x2 and x1.5 (dotted feel). In order to change the multiplication factor, keep the TAP footswitch pressed until you see 2 TAP LED blinks for the x2 factor or 3 TAP LED blinks for the x1.5 factor.


CHOP FEATURE:
While in the Amplitude mode and with the Square LFO selected, you can activate the CHOP effect (kill-dry) which effectively alternates between sound and complete silence. While in the aforementioned settings, simply turn the Depth potentiometer all the way up (to the right) for the CHOP effect to kick in.
