Welcome to my profoundly humble page. :) I've been building stompboxes for a few years now and have found a few sites to be of tremendous help. I reserve the right to add a little window dressing here one of these days.
General Guitar Gadgets - If you've never built your own stompboxes before then this is a great place to get started. You can buy complete kits or just a ready to solder(RTS) printed circuit board(PCB).
GEO - Guitar Effects Oriented page has a plethora of useful information for the neophyte and more technical builder alike.
DIYstompboxes - Home to a great little net community of fellow effects enthusiasts. This is the place to ask good questions.
runoffgroove - Runoffgroove.com is home to many of my favorite projects including some more analog feeling takes on nice amp tonestacks adapted as distortion pedals.
Technology of the Tube Screamer - Excellent article at GEO about my favourite overdrive pedal. Yes, I view it as the gold standard for overdrives.
Small Bear Electronics - Small Bear is an excellent place to find just about ANY part you might need for your next project.
Mouser Electronics - Mouser is an exceedingly reliable seller of general electronics components. In my experience their shipping is usually quite fast.
