Audiofab is pleased to announce the release of the Frequency Distiller Special Blend, a high-quality, dual-channel filter pedal designed specifically for bass guitar. Inspired by the iconic Alembic Superfilter SF-2, the Frequency Distiller distills that sonic DNA into a compact, road-ready format with modern upgrades and intuitive controls. The Special Blend incorporates an enhanced filter design that is more faithful to the original, delivering classic resonant tone, along with a powerful stereo input mode.

Each of the pedal’s two independent channels includes a switchable high-pass, low-pass, band-pass, or notch filter, a filter gain control, a sweepable frequency range, and a resonance control—perfect for sculpting everything from subtle tone shaping to dramatic, synth-like filtering. The channel mode switch allows players to engage either filter (A or B) or both filters in parallel (A+B mode). In all modes, a clean blend control adjusts the level of unprocessed signal mixed with the filtered output.
