The classic. This is the original unmodded version with input and output buffers intact :o) Note, the layout has been done with 2N5088 or 2N3904 transistors in mind and that matches the orientation shown. If you use anything else, check the required orientation for the transistors you use to make sure the pins are C B E from top to bottom.
Slightly more compact version with external switch which will give you stock TS808 clipping, red LEDs for a more aggressive distortion and a centre "diode lift" position which will be louder and cleaner than the other two positions:
(The kit is for the top layout, add a 3 position on/off/on toggle and two red LEDs if you want to build the version with external switch)
