Lastgasp Art Laboratories is a Tokyo-based builder of unconventional effects pedals and noise-oriented electronic instruments founded by experimental noise performance artist Hirofumi Uchino, whose sound project Defektro operates as the sonic arm of the laboratory. The company designs hand-built pedals aimed at experimentation, noise-making, and sound art rather than conventional tone-shaping.

Their catalog leans heavily toward fuzz, oscillation, and textural effects. Notable pedals include the Super Oscillo Fuzz, the Misty Cave analog resonance echo/reverb, the Multi Noise Processor, the Gomorrah subharmonic fuzz, the Octavella upper-octave feedback fuzz, the Sandstorm envelope-controlled white-noise generator, and the Thunder Box (Donsharizer), which scoops the mids to produce the Japanese "donshari" low-and-high-frequency sound.

Alongside effects, Lastgasp Art Laboratories operates as a small record label releasing noise and experimental music, reflecting the founder's roots in Japanese experimental performance. The pedals are distributed internationally through boutique retailers such as Perfect Circuit, Electric Mojo Guitars, and LEP International.

Lastgasp Art Laboratories has 30 products cataloged on Equipboard, including Fuzz Effects Pedals, Filter Effects Pedals, and Boost Effects Pedals. Their gear is featured by 11 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Josh Klinghoffer, Lee Malia, and The Edge. Most Lastgasp Art Laboratories products sit firmly in the high-end, boutique range.
