Electronic Audio Experiments Greathammer Bass Driver
Electronic Audio Experiments · pedal
The Electronic Audio Experiments Greathammer is a bass driver and overdrive pedal built in the United States, designed to provide harmonically rich saturation for bass while preserving the low-end definition and fundamental that bass players require. Like other EAE designs, it uses discrete analog circuitry for organic harmonic character and dynamic response. The Greathammer suits rock, metal, post-punk, and progressive bass contexts where a driven, defined, and harmonically complex bass tone is needed in high-volume ensemble settings.
