Here's my latest offering... mind after seeing some I'm in awe...
Still need to add decals / labels...

needless to say, all parts available from yours truly 
Sweet build, man. Diggin those knobs! Where'd they come from? I also like the gut shot. I did the same thing with the modular header pieces on a bigger multi-effects unit that I built awhile ago. Makes it really easy to take the circuit out and tweak. What I would do to take it a step further (if you haven't already) is create a tweaking/testing device that uses the same headers so all you have to do is disconnect the circuit from your pedal and connect it right to the tester.
For my stuff, I built a little breadboard unit that is basically the beavis board...

and then I also built a separate tweaking unit that has 4 sections of tweaks.
1) resistance - I have two rows of pots, linear and audio, with values of 1k, 10k, 100k, 500k, 1M. Each row is wired in series which allows me to get any resistance value.
2) capacitance - Since variable caps are a little harder to come by, I had to use fixed value caps with rotary switches. So I have (4) 12-way rotary switches and (1) 4-way rotary. Each 12-way has a different set of caps (electro, ceramic, 2 sets of poly film since there were a lot more values to choose from). Then each position on the 4-way goes to a different switch.
3) transistors - This is simply a 3PDT switch with each side wired to a 3-pin transistor socket and the center wired to hookup wires. This gives me the ability to A/B test trannys which is especially useful in fuzz/distortion pedals.
4) diodes - I have (2) 10-pin DIP switches soldered to a small piece of perf board and each pin is connected to a different diode. The 2 DIP switches have matching sets of diodes so I can test with two of the same. This is great for testing different diodes in overdrive/distortion circuits that use a diode clipping stage. One cool thing that I did with is was I built a tube screamer for a buddy and I used the diode test to find the 4-best sounding pairs and then hooked them to a 4P2T rotary switch to make a "clipping color" switch.
Each section of testing has an "in/out" using solid core hookup wire so I can attach it directly to the breadboard on my other unit. I'll try and post some pics of it later.
