Guitar FX by the DoomMeister
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

If you truly want build a custom looper I would start of like this ADC<Micro controller (custom firmware, the fun bit)<Buffer memory<Micro controller<DAC. It probably is quite possible however I would think it be much quicker (even if you have to save up for 6 months) and easier to lash out 250 squid on a Jam Man or Line 6 unit. Not as satisfying I grant you but would end up with a road worthy bit of kit and a lot of free time to make some other killer bit of kit.

Your distortion pedal there are two things that spring to mind, I am sure that you have checked your work and there are no dry (solder) joints present. I will answer to be polite but really your question should be to the maker of the first instructable which I think was this one.
1) Sorry if this sound obvious, but have you tried a new battery. Old batteries often change the sound of a distortion pedal. This is due to the increased self resistance as much as the lower voltage.
2) That the design of the pedal is not a great one. The LM386 chip is one chip power amp not an op amp which is really what you want (a 741 chip or 4558), It will distort an amp for sure but can also put out enough level to power a speaker in its own right. I would suggest that you find a datasheet for the chip and put a 10 micro farad capacitor (30v or so) in series with a 2 k Log pot between pins 1 and 8 to give you a gain control.
The circuit in the instructable seems a less advanced version of this.
3) Try a different circuit I would suggest a similarly simple such as this.
I have generally found home built FX to be as reliable as any shop bought one and have the added advantage that you can tweak them to sound even better.

The finish on most of my stomp boxes is just car spray (celloulose/acrylic) with a good sanding and clear finish. The lables are waterslide transfers printed on an inkjet, you can get special paper for this. One of the TS808's has an etched finish , there should be some good tutorials on the web, if not this site.
