Audiofab offers specialty guitar and bass effects, handcrafted in Waterloo, Ontario, Canada. Our goal is sound that inspires: every pedal is designed, built, and tuned to move players to create and perform, whether on stage, in the studio, or in the practice room. Our approach is evolutionary rather than revolutionary. We start from what has worked over decades of effects design, then ask what happens when a proven foundation is reimagined with modern techniques.

Featured Pedal
Frequency Distiller Special Blend
Alembic SF-2-inspired dual filtering, now in stereo.
Two independent channels, each switching between high-pass, low-pass, band-pass, and notch, with resonance and a clean blend per channel. Run one channel alone or engage both in parallel for filtering that is epic. New stereo input mode lets you process two pickups independently.
"An absolute tone monster and something I've dreamed about for like 25 years."
