I am pretty proud of this one, this is the first board that I drew up and sent out to be fabricated. Its based on a Telenordia TA-100 germanium overdrive. It has 2 1N34A clipping diodes and 3 2N404 transistors. I am pretty happy with how it turned out. It has a nice mild OD sound for the first part of the gain range, and towards the top of the rotation, it has some nice breakup to it. I added a relay-bypass to it, just to make it a little fancier :)

Nice build man. Who doesn't love a Terminator reference?! I though it was gonna be a fuzz but OD would have been my next guess. Great looking PCB and Pedal.

Nice one! Dig the layout, too.
That the mictester bypass?
Its the RG Keen Relay Bypass, using a CD4069. Here is the OSH Park link:

I like this one, so now I need to look into this circuit to see how it sounds! Is it picky about transistor gains or anything?
The only PNP trannies I had on hand were a Tone Bender set, so 70 HFE for Q1 & Q2, 130 HFE for Q3. It would be interesting to see what other gain ranges do for the circuit. To be fair though, what is in there does sound pretty good.
excellent job!
i have a bunch of germanium PNPs and diodes slowly making their way over so i may well check the ta-100 circuit out
