Hi!
Here's layout for
D*A*M - FUZZ rong FR-69.
Pot values are not confirmed

- especially 'Depth', but 250K should do the job. 100K or 500K should work fine, too.
If anybody can confirm exact value that would be great.
Enjoy!
Peace,
b

Info about transistors gains and tone pot value:
Solidhex wrote: I've been messing with some old house numbered RCA's. Same package as the ones in the pics. The spec sheets on the originals state that q1 is usually around 120hfe and q2 around 65hfe. So far the best sound has been a 200hfe in q1 and 80hfe for q2 both with around 100 leakage.
Sticking lower gains in q1 sort of makes the sound dull. Less gain, less top end. The 22k resistor that goes from the .002 to ground (R6) is sort of annoying. It bleeds a fair amount of the q2 signal to ground. Probably to even out the volume of the two ends of the tone pot. I've seen schems calling for a 33k volume pot but that seems like it would hurt the output...probably go with the 500k.

Just don't get the hype..............Build great pedals.....That's really cool but, the prices are just silly.

Another refreshed layout with full off-board wiring.
