Here's a demo of the noise box you can make in my workshop at Supersonic. This is actually the first version. The new version we'll build at Supersonic features a few nice tweaks, making it more flexible and playable.
It may not sound that heavy in this video as the audio is recorded using the internal speaker on my camera but believe me this is one dirty little noise box!
If you want an idea of what happened the last time we built these, check out http://www.thereminday.co.uk
Hope to see you there!
