With the A/B/Y switch you can easily switch one signal between two single outputs (A/B), or put it on both outputs (Y). The first switch switches between outputs A and B, the second switch (Y), switches the input on both outputs.
Wiring layout: abywire
The A/B(C switch can be used to switch between one signal on 3 different outputs or 3 signals on one input. The first switch (A) switches between A and A/B, the second switch (B/C) switches between B and C.

The Germanium Face is a project based on the classic Fuz Face, with 2 selected germanium transistors. It works with positive ground and can´t be connected along with other pedals (which mostly are using negative ground) on one power supply.

Das Plus is a distortion based on the good old Distortion+. It has some minor improvments, it features a 1M pulldown resistor (R1) and a oscillating preventing cap (C5).

The Tubescreamer is one of the most played and most liked overdrive pedals. With this project you can build two classical versions TS9 and TS808. TS9 and TS808 only are different in 2 resistor values, what sounds better is a matter of taste.
If you want to build the TS9, just select the values for R15 and R16 from the table, of course the same for the TS-808 variant.
