EarthQuaker Devices Erupter fuzz pedal in immaculate condition. No visible wear or marks. Pedal only: no box, no paperwork. Photos show exactly what you get. The Erupter is a single-knob silicon fuzz (Bias) with a buffered input and transformer-based pickup simulation, so it behaves consistently anywhere in the chain and cleans up with the guitar's volume knob. Fixed output and gain, relay-based true bypass, all-analog signal path. Built in Akron, Ohio.
