Product Description

Psycho HP/BP/LP filter with a sleek, laser etched enclosure. Can be pushed past the limit into octaves up, down, and folding envelopes. Its medical grade IC chip creates a hyper precise filter that sounds like no other. The Evil Fuzz takes signals into a much darker dimension, offering an inverted compression toggle to push sounds even further into the depths. Using the CV/Expression input, you can control the filter cutoff frequency with an expression pedal or synthesizer.  


Filter Freq: Cutoff frequency of the filter. Numbers shown are in Hz.

Filter Output: Volume of the filter section of the pedal.

Filter Selector: Selects between the different filter types -  Low Pass,  Band Pass, and  High Pass.  

Filter Resonance: Sets the resonance of the filter in conjunction with the Resonance Switch. WARNING: Will self oscillate at high levels!

Resonance Switch: Sets the range of the Filter Resonance knob between Normal and High.

Fuzz Output: Volume of the fuzz section of the pedal.

Fuzz Type Switch: Choose between two different fuzzes -  lower for a cleaner, more driving fuzz,  higher for a blasted out, blooming, insane fuzz.

EXP/CV Input: Plug in CV control (~0-3.0v) or an expression pedal for external control of the Filter Freq knob. The Filter Freq knob sets the range for the EXP/CV input.


Dimensions: 7.5" x 4.6" x 2.5" (including knobs and jacks).
