Latent Lemon Audio is a small, hand-built guitar and bass effects pedal company based in Luton, England. It was founded by Justin Saban, a sound engineer and producer who worked at London studios including Fortress Studios and Southern Studios, and began building his own pedals to use on recording sessions before bands started requesting custom builds of their own.

The brand is best known for the Hurts, a Harmonic Percolator-style fuzz capable of sub-octave fuzz, controllable feedback, and lighter grit or transistor boost tones. The Hurts notably appears on the floor in the Steve Albini segment of The Pedal Movie. Alongside it, the company offers the Bass Brassmaster, a reinterpretation of the 1970s Maestro Bass Brassmaster octave fuzz available in silicon or germanium versions, plus custom one-off builds.

Production is small-batch, with pedals sold directly and through a handful of international resellers including Northern Stompboxes in the UK, Pedal Markt in Germany, and Mocha Earth Music in Australia. Several earlier designs such as the Supersonic Fuzzhound, Crazy Horse, Scrambler, and Edward The Fuzz have been retired, while models like the Hoo-Tron-3 and Luton Fuzz cycle in and out of availability.

Latent Lemon Audio has 3 products cataloged on Equipboard, including Fuzz Effects Pedals and Bass Effects Pedals. Their gear is featured by 3 artists, with the strongest followings in Rock and Metal. Notable users include Christian Lembach, Johan Högberg, and Carl Geary.
