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
