[782] Cheap Fuzz Again

Cheap Fuzz schematic

A fuzz circuit from the mid-1960s using 4 germanium transistors.

If you click on the image above, you can get a full size view of the schematic. I’m not sure how well this performs as I have not built it, but of particular interest is the tone control in the bottom diagram. It is the same basic circuit as the Stupidly Wonderful Tone Control. The link to the Ampage site where the SWTC was posted is no longer working but you can see it on my SWTC2 page. Great minds think alike!

Of further interest is the use of the D1 diode on the base of TR2. I’ve seen that idea used as well – good ideas keep popping up again and again.

Also, there was a letter with comments about the circuit that you should read if you plan on trying this design.
