The Greer Tarpit Integrated Circuit Fuzz Machine captures the vintage bite of classic Big Muff models with the signature Greer appointments that set this company's pedals on another level. Crafted on the foundation of a dual integrated circuit design, this pedal features a simple three-knob control scheme that does much more than meets the eye. Playing with the sustain and fuzz allows you to go from a low, sputtering germanium attack to a tight buzzy onslaught with a sensitive volume control that keeps the sustain/fuzz settings at the fore without getting muddy at higher volumes.
