Fuzz Factory

Well, this is not new as there have been so many FF projects lying around the net. And I just decided to do a layout since it's so very easy. Pots are mounted directly to the PCB and should be placed vertically like those in original zvex's. I used 125B type box with no problems. Please note that transistor values are my own choices. Components below the "STAB" pot(ie 4.7K, 390 ohms, and 22uF cap) is an LED anti-pop circuit.

  1. hi rapid, i found some errors in this layout,gate and comp pots are reversed, and stab pins 1 and 2, to +9v, i think.
    thank

  2. Those are intentional..it sounded very nice by the way in my build..

  3. I tried it out and sounds really nice.. didn't notice the reversed pots.. just messed around will all of them. Pretty interesting sounds.. oh and BTW i used AC128 (had a few around)

    Thanks dude!

  4. wait, so with the reversed pots do the settings get changed too? like would these settings still work or would it be in reverse? http://img.photobucket.com/albums/v294/onetubetone/Page1-2.jpg

  5. I'd say totally reversed in this layout but if you rather have it like the original all you have to do is cut some tracks and make some bridges on the pots. (and then you can follow that chart) I think it's more fun to experiment because you will also get different results with dif transistors..amp pickups etc. you can still go by the chart 1:00 reads 11:00, 2:00, 10:00 and so on.

  6. The lead switching is already on the board? Just wiring a true bypass on a dpdt will make the led go on or off?

  7. how the cable channels if using switches 3pdt.i'm still an amateur

  8. los pines de los potenciometros de comp y gate estan invertidos, pero suena igual al original

  9. I'm going to build this but I have a couple of questions. There appears to be some unused pads on this layout, such as one connected to Vol lug 1, one connected to lug 3, and one connected to stab lug 1 and 2. Also, I assume the other side of the led goes to ground. Thanks for the help.
