ThorpyFX Wopr
ThorpyFX · pedal
The ThorpyFX WOPR combines a more aggressive variant of Thorpy's Fallout Cloud Muff-style fuzz circuit with a Rangemaster-inspired treble booster in one pedal, delivering a ferocious, biting tone with extra treble zing on top of thick Triangle-Muff-style fuzz. It ranges from bright, ice-picky, cutting fuzz tones to a woolier, sludgier voice suited to doom-metal riffing, with active Treble and Bass controls allowing both additive and reductive tone shaping. The Boost side's Range and Boost controls let players dial in different flavors of Rangemaster-style treble boost, stackable with the fuzz side for an especially explosive, aggressive combined tone. It suits players wanting an aggressive, treble-forward fuzz with real boost versatility built in.
