I had to try a few different cap values because the one I build got really dark.
Forgot to mention... ironically, though I couldn't get it to sound the way I wanted, it still ended up on my pedalboard. I actually keep it on with a boost in front to brighten it up. Just curious if anyone has any ideas to make it more useable on it's on.
Yikes - that must be the simplest overdrive ever!

And it sounds exactly like you'd expect a single silicon transistor driven to cutoff with no filtering or buffering to sound. ::)
There's design simplicity and then there's laziness.
:D haha. I still can't imagine 2 mojo caps making that circuit worth 160
Maybe i'll just add some switches and make it an OD/boost/fuzz box

They're not even really mojo. They're trash Russian caps, which they probably picked up for almost nothing on Ebay. They're just high voltage.
haha I'm not surprised.
I replaced the 2n5088 with a metal can 2n2222a and it sounds a lot better now. Still a little on the dark side, but with the gain low, the clipping sounds more natural, and less like a low gain fuzz, and run-on sentences are awesome.
