From the vendor

This is a big build…but its well worth it!!!

To quote EQD “A monophonic analog harmonizing PLL with modulation. It takes your input signal and brutally amplifies it into a crushing square wave fuzz tone that is then multiplied, divided and modulated to create a wild, yet repeatable, three-voice guitar synthesizer.”

The sounds you can get from this board are wild!! Take your time and its worth the effort.

Controls:

This things has A LOT of controls!

Mixer:

Square : Controls level of square wave fuzz

Sub : Controls level of subdivided frequency

Oscillator : Controls level of multiplied frequency

Level : Controls overall output volume

Subdivider:

Sub : Rotary switch – Sets the interval of subdivided voice

Sub Root : Toggle switch – Selects the source of the subdivided root

Multiplier:

Oscillator : Rotary switch – Sets the interval of the multiplied voice

Oscillator Root : Toggle switch – Selects the source of the multiplied voice

Modulation:

Glide : Toggle switch – elects between Portamento / Vibrato pitch modulation

Rate : Controls the rate of pitch modulation

Size:

Designed for a 1590XX with top mounted jacks
