DeadAstronaut Space Patrol Fuzz

For Fuzz Friday here's DeadAstronaut's take on the good ol' Big Muff. It features a toggle switch (Fat/Thin) that changes the output capacitor from the first stage, and a rotary switch (mode) that changes the sound type. In the designer's own words:

It's basically a classic big muff with fat/thin switching, plus 3 other modes for synthy, buzzy, octavey, duck and swell type sounds...by switching diodes and collector resistors. Rather  like a bias control on a fuzz face...but for both collectors.

 Here's the schematic for reference.

      It's not in my dropbox. I linked to what DeadAstronaut had posted over on DIYSB, but it looks like he's moved it. Sorry!

      As long as it's the correct value, the bands shouldn't matter too much.

      Can't do it with a toggle. Stick with what's indicated in the layout.

    does anyone have a graphic for the switch? I see that 9-11 and 12 should be reversed as per shematic. do you connect a and b together and then 9-11 pins soldered together? and 5/6 also? thanks anyone for help...peace
