S&S industrial led'sCircuitbenders.co.uk was launched back in 2001 after a chance accident with an old Speak & Spell machine and a soldering iron opened up new realms of sonic destruction and audio carnage for circuitbenders founder Paul Norris. This site was the first website in the UK offering circuitbent machines for sale, alongside a wide range of custom modifications and upgrades for electronic toys, drum machines, synths and samplers. Our machines have been featured on music from artists as diverse as The Chemical Brothers and Bloc Party, along with hundreds of producers and artists worldwide.

The term 'circuitbending' refers to the technique of rewiring the electronics of just about anything that makes a noise to create a machine capable of sounds the original designers would have never thought possible. Anything from dirty twisted percussion and 8 bit computer glitching, to droning alien soundscapes and crushing walls of noise can be coaxed from the most unlikely of sources with nothing but a soldering iron and a lot of patience.

For details of all our standard modifications for various machines take a look at the links to the left. If your machine doesn't appear there then don't worry, we are usually willing to attempt to modify just about anything within reason. On machines we've never modified before we can often offer you a cheaper 'prototyping' deal on mods that we can then offer to other people. Just get in touch and let us know what you've got. The main requirements for a machine to be circuitbent is that it makes a noise and it's not likely to kill us in the process!

If you want to discuss anything circuitbending related or you want to try modifying your own machines and need some advice then you can join our circuitbending and electronic audio DIY FORUM where you can pick up some tips, discuss circuit bending technique and show off your latest modified machines.
