Circuitbenders is a UK-based electronic audio modification shop and small-batch instrument builder operating under Pill Shovel Productions, active since 2001. The company specializes in circuit-bent and modified vintage gear, offering installable modifications for machines like the Roland TR-707/TR-727, Korg Kaoss Pad, Korg Poly-800, Yamaha R100 reverb, and the Texas Instruments Speak & Spell, alongside custom-built and bent machines sold direct from their workshop.

Alongside the modification service, Circuitbenders develops and sells its own line of devices and DIY kits. Releases include the CB55, a clone-and-expansion of the Roland DR-55 drum machine, the TR7X7 ROM/pitch-mod kits for the TR-707 family, the Demon Seed fuzz/distortion pedal, the Hate Echo delay, the Clock Shuffler, and the AC CPL Eurorack channel-offset module.

The shop has built a niche reputation in the circuit-bending and DIY electronic music community for treating bending as a serious instrument-design discipline, with discussions of its work appearing across forums like Mod Wiggler, Gearspace, and Vintage Synth Explorer.

Circuitbenders has 1 product cataloged on Equipboard, including Fuzz Effects Pedals.
