The Electronic Audio Experiments Greathammer is a bass-focused overdrive and preamp pedal that delivers massive solid-state-inspired punch, aggressive grind, and deep low-end response. Inspired by legendary 1970s Canadian bass amplifiers, the Greathammer captures the unmistakable piano-like attack and crushing character associated with classic noise rock while expanding the tonal range for modern players and heavier tuning styles.

Designed for bass but equally impressive on guitar, the Greathammer offers everything from subtle warmth and edge-of-breakup grit to full-on saturated distortion with remarkable clarity and note definition. Its responsive controls allow players to shape attack, low-end heft, and midrange character while maintaining a connected, amp-like feel without relying on a traditional clean blend. The Greathammer works exceptionally well both in front of an amp and as a standalone preamp solution.
