This is just a little overdrive circuit I threw together the other day - I had an MXR octave fuzz that refused to work so I gutted it and made this thing to fill the box.
I didn't use a schematic or any pre-planning I just threw it together and hoped it did something and it did and it was quite a pleasing something. I will trace it so I've got a schematic to post at some point but until then here is the layout
The first 10 seconds is the guitar with no overdrive on
