FORTIN: Fuzz

Request - here you go & I hope this is what you were after.  Could shave off a column or two if that's a bother.

The Fortin is a pretty stock silicon fuzz face with an input blend, a 10k trimmer in place of the usual 8k2 resistor and a 100n cap on the output.  A few smallish caps on the collector and base of transistors to tame the fizz.   It's not unlike the D*A*M Drag n Fly DF-05 and no doubt a few other fuzz faces with an input blend.

Schematic can be found here

Thank you very much Andrew, I didn't realise how useless the sweep was on the Fuzz control - might benefit from a different taper pot

Hvae you already made it? That's normal on a fuzz face. Reverse log is often used as a replacement.

Not made it yet, I had only heard demos of it. That video you linked was the first I had seen where he actually showed what the controls did, will definitely throw a C pot in.

Got it - and I guess you could always replace the 1k pot with a fixed resistor and make the 10k trimmer an external pot. Easy enough to experiment with

Thank you for the layout, just finished it. I changed the fuzz pot for a 1k reverse log and the sweep is much better. Really like it, to be boxed.

Great - should be able to use this layout for quite a few variations of fuzz face. But you probbaly won't need another now. ;-)
