Since the early 1990s, MOSFET circuits have remained one of the pedal industry’s most elusive white whales — not because the circuits are difficult to source or produce, but because it’s a difficult distortion to execute well. If that weren’t a daunting enough challenge, the desire to innovate or evolve the MOSFET-fueled design — while retaining the distinctive grit that’s made a particular ’90s pedal such a desired addition to guitarists’ pedalboards — has proven to be a near-insurmountable hurdle. Never one to shy away from a challenge, Wampler took up the mantle of this seemingly Sisyphean task, meticulously studying the decades of MOS-style distortions and permutations to capture that MOSFET magic. After multiple bouts of painstaking R&D, Wampler has emerged with the Mofetta, a US-built overdrive pedal that brings the time-tested tones of the lauded early-’90s device that inspired it well into the 21st century, including the classic 3-band EQ, and augmenting it with a texture switch to expand its sonic terrain even further. Sweetwater’s Oak Ridge rex, Don Carr, deploys the Mofetta through a kaleidoscopic array of guitar and amp pairings to take this Wampler wonder to its limits. Check it out!
