In my random pedal-googling I came across this distortion circuit, and thought I'd see if I could build it:

I'm a bit of a noob, and of course this circuit isn't very well supported (no real instructions, slightly confusing circuit diagram, no schematic, no PCB to purchase). I put the diagram and PCB layout in photoshop so I could see where the connections actually were, and came up with this:
Anyway, I fiddled around for awhile (I'm embarrassed to say for how long...) and finally got it to work on a breadboard
It actually sounds pretty good. Better than the other circuit I breadboarded last week. I didn't have electrolytic caps in most of the values it required, so used ceramic caps instead. I don't know if this makes a difference?
From what I understand a pot between pins 1 and 8 of the first IC gives you control over the gain, right? I might stick one in tomorrow arvo and see what happens, and then I'll try to solder it to some veroboard and box it up.
