Rainger FX Chop Fuzzz

Rainger Fx · pedal

The Rainger FX Dr. Freakenstein Chop Fuzzz is an all-analogue gated fuzz from London builder David Rainger, and the most advanced pedal in the Dr Freakenstein line. Its core is the massive full-frequency fuzz that made the original famous: earth-shaking lows, searing highs and enormous sustain, kept tight and controlled by a built-in noise gate that stays impressively quiet between notes. Around that sit Overtone, LFO and Chop sections -- Chop being a square-wave tremolo, optionally synced to the LFO, producing bubbling, gurgling, stuttering and outright bizarre rhythmic textures. A tunable drone facility reaches ring-modulator tones, and a pressure-operated expression pad gives wah-like sweeps underfoot. A spooky-eye meter displays input level along with LFO and Chop activity. Effectively a fuzz-centred multi-effect for experimental players.
