Wattson EFY-6

For Fuzz Friday, here's the Wattson EFY-6. This is Wattson Classic Electronics take on the classic Shin-Ei FY-6 (also known as the Univox Super Fuzz) and stays fairly faithful to the original circuit, but with a few straight forward and useful mods. The schematic and a full explanation of the circuit was posted on FSB by amp_surgeon (the guy behind Wattson). The originals have the Balance pot as a trimmer, but I've included pads for either a trimmer or external pot. I've laid it out for board mounted pots to fit in a 125B with top mounted jacks.

  1. Sweet. Any thoughts on replacement for NTE109? 1n34a? 1n270?

    Btw, I've got the schematic for CAF in case you've missed my reply :)

  2. 1N34 or 270s would be a good sub. And don't worry, the CAF is coming ;)

  3. Hi, can you please make layout of this delay with all the pots and rotary-s boardmounted? http://tagboardeffects.blogspot.ru/2015/10/sagan-delay.html

  4. Great work friend as always, I didn't see octave multiplexer or similar kind of pedal, there are a lot of octave-fuzz pedals in this blog,I'd like to see unique octave pedal clone from you.

  6. Hi,

    You can mark it verified, though the balance knob acts kinda strange...

    I'll post my build pic later.

    Thanks!

  8. Oh, man! I've wanted a Wattson Classic EFY-6 so very badly, and they evaporated! THANK YOU for this- I may have to build one, eh? I just happen to be building a B.Y.O.C. Scrambled Octave kit (Ampeg Scrambler) this very day! Perhaps I'll wind up slapping together an EFY-6 clone in the near future, as well...

    I also once owned an original JAX/Shin-ei FY-2 Companion Fuzz, decades ago; it was an insane, pumping breathing sandblaster of a fuzz! I didn't know what I had, nor appreciate or understand how to use it at the time...

    Thanks again! I'm stoked that I might still be able to have and use an EFY-6'er... Too cool.
