Home Brewed Instruments
Don't worry - not some boring run down of all the gear I use. These are some of the customised and home-brewed instuments I have made. Part Heath Robinson, part Harry Partch.
For most of these there is an MP3 audio file of a brief demonstration of the instrument which can be accessed by clicking on the (listen) links.
