ElectroGrave is a boutique effects pedal and synthesizer maker based in Nagoya, Japan, operating out of a small workshop in the city's Higashi-ku ward. The brand focuses on experimental and noise-oriented designs, producing hand-built units in limited runs and selling direct through its own shop as well as specialist pedal retailers.

The company is best known for the Ripper Fuzz, a gated fuzz circuit inspired by the Roland BeeGee, an obscure Japanese fuzz from the 1970s. The Ripper Fuzz's side-chain style gate produces abrupt, synth-like note decay that has made it a favorite for bassists and guitarists chasing unconventional textures. The range also includes the Ripper Fuzz Dry Blend, the Quad Oscillator, Beat Happening, Experimental Fuzz MkII, Superposer, Search and Destroy, and Sonic Duel Box.

Across its catalog, ElectroGrave leans toward tools that blur the line between effect pedal and electronic instrument — oscillator boxes, tone generators, and heavily gated fuzzes aimed at noise, experimental rock, and avant-garde players rather than mainstream tone shaping.

ElectroGrave has 3 products cataloged on Equipboard, including Synthesizers and Fuzz Effects Pedals. Their gear is featured by 4 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Kazumoto Endo, Hisako Tabuchi, and Toshiji Mikawa.
