Greer Tarpit

Greer · pedal

The Greer Amps Tarpit is a heavy, thick fuzz pedal from Athens, Georgia boutique maker Greer Amplification, named after the prehistoric tar pits that trapped ancient megafauna, evoking a dense, slow, enveloping fuzz character that pulls notes down into saturated thickness. The Tarpit delivers the kind of heavy, dense fuzz character associated with doom and sludge metal, where the weight and deliberate heaviness of the fuzz tone is the primary aesthetic. Greer builds handmade boutique effects in Athens, GA, and the Tarpit Fuzz represents their heaviest, most sludge-oriented fuzz design.
