Indeed. I've already tried building one Pedal myself, using a schematic for a "Dunlop MXR Custom Badass '78 Distortion". I tried it in-store, and loved the sound, but sadly it was beyond my budget at the time. Then a friend of mine, whom I met at the place where I study electronics, suggested finding a schematic for the pedal, buying all the parts needed and then build it myself. Cut the price down to about 40% of the retail-price :) Had a few problems with it, though, since some of the components lost a few legs when I tried building the pedal. My next project after building an amp might be to get a bunch of enclosures and some more components and try building more pedals. I've found a few simple designs that I think might be worth trying out.
