Parasit Studio is a small, independent guitar effects pedal maker based in Umeå, in northern Sweden. The company is run by Fredrik Lyxzén, a sound engineer who designs and builds the pedals alongside playing in bands. The brand sells both fully assembled pedals and DIY kits, with the latter distributed through partners such as Musikding and Synthcube.

Parasit Studio focuses on unconventional, experimental circuits rather than traditional drive and modulation staples. The lineup leans heavily on guitar synthesizers, bitcrushers, ring modulators, and CMOS-based fuzz designs, with releases including the Arcadiator and Super Arcadiator fuzzes, the Into the Unknown guitar synth, the Multiwave and 1985 guitar synths, the 8-Bitar, the Console 84 8-bit synth, the C19 Databus Drive, the Sidescroller, the Higgs Particle Phaser, the Green Currant Tremolo, and the Theremin Fuzz.

The pedals have built a niche following in the noise, lo-fi, and experimental guitar communities for tones that range from chiptune and video-game-like square waves to glitchy ring-mod artifacts and gated synth fuzz, with many of the designs also released as schematics or kits for the DIY pedal-building scene.

Parasit Studio has 6 products cataloged on Equipboard, including Fuzz Effects Pedals and Guitar Synth Pedals.
