Abyss Dweller (OpAmp big muff)

A clone of the EHX OpAmp big muff released in 1978. Known for its agression and less flattened mids when compared to its transistor based brothers.

Great for heavy “wall of sound” tones. It features a tonestack switch that changes the circuit to different styles of filters (normal, highpass, lowpass)

Controls

Blood - controls output volume

Flame - controls level of gain

Horns - controls tone of pedal, switchable circuits via toggle (standard BMP, Highpass, Lowpass) 

*Please note that this pedal is B-stock and may have some minor marks or scratches, but is in full working order. All B-STOCK are FINAL, the product is sold AS IS.*
