I'm just getting started with digital pedals. I'm going to be building an arduino based pedal with step by step instruction from another site. I have no experience in digital guitar pedals. I'm pretty gung-ho about effects pedals right now. I've been laying out some designs for future pedals. Anyway, I have a couple of questions about using ICs for guitar pedals. First off, what's a good chip to start off with? Are there special audio chips, or will just about any old microchip do? And, what interface do you use to program these chips?
while i haven't done any digital myself, check this out

and slacker seems to be starting up a fresh thread which sounds promising

Thanks for your help, Kingswayguitar. That's exactly what I needed!
