Roland AF-60 BeeGee

Happy Fuzz Friday, all. Somehow in 10 years of laying out fuzzes, I've never done this one. Here's the  Roland (pre-Boss) AF-60 BeeGee fuzz. Originals use semiconductors you probably don't have in your parts stash, but nothing in mojo territory, so modern equivalents will work just as well. Fairly simple circuit with a couple transistor amplifiers, an opamp stage, hard clipping, and a BMP-style tone stack. Here's the schematic for reference. Easy fit in a 1590B.

  2. very nice work. In which program do you make the perforated PCB designs here? I would be happy if you help

  3. Pal about to verify it, could you confirm 10uF cap in the lower right corner, on the schematic it shows as 1uF

    1. Pal, also the 4n7 cap should be 47nF and the 47R should be 470R. That’s about it

  4. VERIFIED!!!
    I changed the 47R resistor for 470R, the 4n7 cap for 47nF and the 1uF made it film instead of electrolytic. I like the sound and the aggressive tone control this pedal has. But somehow it’s not as loud as many others. I want it louder. Also switched 2N5088 for BC549C with higher HFE. UA741CP and LM741 work pretty fine
