No, Forrest, these men are nihilists. There's nothing to be afraid of.

Haha, nice one, Charles.  ;D  Totally tied the thread together.

Quote from: madbean on January 29, 2017, 08:11:55 PMC1 (from Tagboard) is 680pF on the CF, FYI.

Is the rest of it correct? ::)

I'm not a member of FSB so I can't view the image but if you post it here I can check.

You're missing a 1k resistor between the Tone pot and the 2n2 cap, I think. The first position on the rotary is no clipping diodes, then LED, 2n7000, 1n194 and finally BAT41. Good work!

IIRC D12 came directly off the 9v supply rather than after the PTC. I seem to remember we had an issue with noise otherwise. But I might be mis-remembering that.

Nice trick with the fuse, BTW. You get the advantages of the crowbar and if polarity is reversed, nothing burns up. Mind sharing which one you use?

Yeah I wasn't really hip to that before but Jerry suggested we do that for all our pedals. This is the one we use:

Darlington front end? I'm guessing it isn't just for the gain which is limited by 2x emitter resistance. I'm intrigued enough to check out the clipping it produces.

It's been so long now that I might be remembering this wrong, but I believe we originally had Q1 configured quite differently and then rejiggered it to remove oscillation when Fuzz and Volume were both dimed.

That's a great looking (and sounding, based on demos) circuit, Brian.

Now that the schematic for your board is on FSB, it is time for you to start selling Clusterfuzz kits!
