Hello,
Thanks - this looks like my kind of site with a ton of guitar info. I'll let you know how this turns out. I have built several guitarish instruments using a walker, wood, and contact mics. Here's a link to a pict if your interested. My new idea will incorporate some of those ideas along with some new stuff including some oscillators and a lo-fi sampler.
