The other classic. This again is as per the original. 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:

For tips and tricks have a look at this fantastic build video from LoHi Sounds on YouTube. He's done a great job of the build and an even better job of showing what's required for the full process. Thanks for the vid!
