Skreddy Pedals is a boutique guitar effects company founded by Marc Ahlfs in 2004, based in Carson City, Nevada. Marc, along with his wife Cynthia, handcrafts each pedal in small batches, specializing in fuzz, overdrive, distortion, delay, and modulation effects. The brand has earned a devoted following for its meticulous voicing of classic fuzz circuits, particularly Big Muff Pi variants and germanium/silicon hybrid designs, often using rare vintage transistors that give each run its own tonal character.

Skreddy Pedals' lineup includes several iconic designs. The Mayonaise, the brand's original flagship, is a faithful reimagining of the early-1970s triangle-knob Big Muff Pi circuit. The Lunar Module is a silicon fuzz voiced for aggressive, mix-cutting leads, while the Screwdriver delivers touch-sensitive overdrive and distortion with a Tweed-amp character. Other notable pedals include the P19 (a David Gilmour-inspired Muff-style fuzz), the Hybrid Fuzz Driver, the Echo delay, and the Cognitive Dissonance high-gain fuzz. Marc Ahlfs is widely regarded as one of the foremost designers of 4-transistor silicon fuzzes and germanium/silicon hybrids, and Skreddy pedals are known for selling out quickly due to limited production runs and finite supplies of select transistors.

Skreddy has 48 products cataloged on Equipboard, including Fuzz Effects Pedals, Overdrive Effects Pedals, and Delay Effects Pedals. Their gear is featured by 12 artists, with the strongest followings in Rock, Pop, and Electronic. Notable users include Dylan Desmond, Cory Hanson, and Billy Corgan. Most Skreddy products sit firmly in the high-end, boutique range.
