The Pinkosa (AKA Carcass AKA Carcosa)

I had a bit of an "oh no!" moment when I plugged it in the first time (before I boxed it) and got silence when the pedal was on. Then I realised that I hadn't put the transistors in yet. Did so, worked perfectly.

Sounds great, I see why the original is so popular. There's a huge variety of sounds in this design. The controls are very interactive and you can get some cool "broken" sounds as well as the more normal fuzz/distortion stuff. If you're thinking of making one: do it.

Pretty straightforward build. I did have to put two resistors in series (first time I've done that) because I failed to get any 510K resistors. I used a 422K and a 91K, nominally 513K and tested as 514K. That's close enough for me. You can see it in the innard shots. Also my footswitch because I find that I prefer to just wire it up than use a breakout board, and finally a special close up of the power connector thingy so as to trigger the haters.

That looks great! I'm prepping for my build on this. Did you need to measure and match hfe's of the transistors?
I measured them, they're all in the range of 315 - 345 hFE as I recall it. I didn't try to sort them, just grabbed 5 out of the pack of 20 I bought and since they all tested in the right general range I just stuck 'em in the sockets at random.
