I have a Casio RZ-1 from these guys (Diabolical Devices). I use the RZ-1 for lo-fi drums and was trying to track down one in good condition on eBay; I happened to find one sold by these guys that was bent and said why not try it.

Anyway, here’s a somewhat lame demo of my bent RZ-1:

It really is baffling that cats are reverse engineering this stuff and able to get decent results through shorting the circuits.
I was introduced to bent circuits in school, but really haven’t even heard the term used in association with sampler type gadgets. Some kid I knew did something with a guitar effect module he had, similar results.
These cats are sharp. Wish I could dissect sound machines to the component level. I can fathom how everything works, but it would be nice to really get the hands on stuff and actually work on a project.
My hats off to those that do.
