Intro: Guitar FX by the DoomMeister
Hand built FX don't have to cost the earth, DoomMeister builds his own.
I don't think that I can add any greatly illuminating Instructables on building guitar FX pedals as there is more than enough very high quality sites out there with both step by step instructions and ready to cook PCB layouts. That's how most of my pedals were constructed. I may however at some point post some general thoughts on the process and also document my pedal board power supply.
So here are some of the pedals the DoomMeister has made both for his own enjoyment and for friends.
Edit - Some links to the best homebrew pedal sites
