Electronic Audio Experiments Greathammer Bass Preamp Overdrive Pedal | No Limit Guitar Co, Idaho Falls
The Electronic Audio Experiments Greathammer is a bass-focused overdrive pedal that brings a distinct flavor of solid-state thunder, with a gain control spanning a full 50dB range that can stay restrained or turn genuinely rowdy. Drawing inspiration from a beloved 1970s Canadian bass amplifier while redesigning entire circuit blocks from scratch, the Greathammer preserves the classic piano-like attack that defined 90s noise rock while expanding into deeper low-frequency territory. This pedal is built for bass players who want everything from tasteful, articulate drive to filthy, down-tuned mayhem, and it works just as well on guitar.
Product Overview
The Greathammer's circuit is capable of far deeper low-frequency extension than the vintage amplifiers that inspired it, all without the unnatural, disconnected feel of a traditional clean blend. It works equally well placed in front of an amplifier or used as a dedicated preamp, giving players flexibility in how they integrate it into a rig. A Bass control offers a post-clipping low-frequency shelf boost of up to +14dB at 100Hz and below, while an Attack control shapes pre-gain tone above 1kHz, tailoring the overall drive response and sharpness of pick attack. A 3-position Notch toggle rounds out the tone-shaping section, offering a full mid cut in the center position, a moderate mid cut when set down, and flat mids when set up, giving players precise control over how aggressive or scooped the pedal's midrange sits in a mix.
Ideal For
Bass players who want solid-state overdrive with deep low-frequency extension. Musicians searching for a bass overdrive pedal with a 3-position mid cut toggle. Noise rock and down-tuned players who want piano-like attack alongside filthy, aggressive drive. Guitarists looking for a distinctive overdrive pedal originally voiced for bass. Players who want a pedal flexible enough to run in front of an amp or as a dedicated preamp.
