Swapping that 2K7 for a 5K pot would probably make a useful fuzz control. Now this really got me interested. But my desk is full Jimiphoton's video on DIY forum is pretty great, so I might have to try this one day. No diodes involved at all dropping the voltage from 9v to 1. It's voltage divider, that drops it from 9V to 1,5V. Don't know what it does to the current consumption though. I plan on using your layouts to make these.

Post by pinkjimiphoton » 09 Sep , cool! I have 12Ks in place of 1Ks at the tone, and it's around unity - with trimmer the one that replaces the 10K at Q2 collector set at about 0. Post by pinkjimiphoton » 24 Feb , these are really good fuzzes, they kinda remind me of a percolator in some respects tonally. Post by LucifersTrip » 08 Sep , I don't mind a bit less output on a fuzz.

With 1,5 voltage i have 1,7 with 3K9 resistor , there seems to be virtually no difference between the sets. I think that was a Hallibar sp?
