SupaFuzz MK1 schematic and layout
For those of you who didn't see this in the Sound and Vision forum.
This is the schematic (unverified) of the earliest Marshall SupaFuzz. It's basically a MK1 with a high-pass filter on the end.
There's info about it in Graham's SupaFuzz Data Dump thread here:

Re: SupaFuzz MK1 schematic and layout
Excellent work! I've wanted to know about this pedal ever since i read the Tone Bender History page, thanks!

Re: SupaFuzz MK1 schematic and layout
schematic and layout are simply wrong..... the 4n7 is not a filter cap instead it is the output cap.FOXFIRE wrote:no output cap?
the filter potentiometer acts as a voltage divider in conjunktion with the 47k and 22k resistor.
Have a look at the guts again.
BTW, OC75 are pnp transistors and NOT npn as shown. The second 5µF electrolytic is drawn in the wrong direction.

Re: SupaFuzz MK1 schematic and layout
I noted in the other thread about the transistors. I couldn't make them PNP with the emitters pointing down in DIY Layout Creator so I just used the NPN symbols. We all know it uses OC75's and well all know they are PNP so I didn't really care.analogguru wrote:schematic and layout are simply wrong..... the 4n7 is not a filter cap instead it is the output cap.FOXFIRE wrote:no output cap?

Really ? Did you search on your computer for a program called "paint" ?SonicVI wrote: I couldn't make them PNP with the emitters pointing down in DIY Layout Creator....

No, I don't have Paint.
Thanks for the corrections. I'll make the changes in my project. I'll flip the wires on the layout as well.
