Stupid questions ahoy! I have a few toy keyboards lying around and have been trying to read up about circuit bending them to create glitchy noisy sounds, so I have enthusiastically taken them to bits and poked their circuit boards with wires to find different sounds... and they do fuck all, the odd crackle and screech here and there but nothing superlofiglitchtastic :/ Can anyone put the art of circuit bending into english to help?

I also have vague dreams about incorporating this type of thing into a guitar, has this been done (apart from the kaosspad thing?)
