Shin Ei 8TR Fuzz Wah

Can't find much info on a description of it, but what I do know is that it a superfuzz  running into a wah. There's literally 1 component value difference in the superfuzz, the rest is straight up identical to the standard superfuzz.






Quick note about the wiring. Just like the Shin Ei 6TR Fuzz Wah I posted the other day, the fuzz comes before the wah, so you'll wire it up according to the dual effect wiring as shown in the offboard wiring tab. You'll notice instead of making this on 1 massive board I opted for 2 separate boards. This will give you more options for placement in an enclosure, by preventing it from being 1 massive board.

  2. Ive actually got a real one of these on the workbench. The guy has taken it out of the wah enclosure and gone with a hammond style. Its developed a nice hum apparently after years of good service. Proding around as we speak.

  3. I have built the fuzz circuit and it works awesomely So it can be tagged as verified. A minor edit is needed regarding the Balance pot wiring. From top to bottom the wiring should be Balance 2, 3, 1.
    Not sure which schematic was used for the layout but it seems to be more similar to the Superfuzz and not the 8TR schematic that I was able to find online although the differences appear to be minor. Loads of saturation and volume on tap! Thanks for putting these layouts together. Very much appreciated.

    1. cheers man. updated the layout. i'll have to check the schematic i have, but remember during this time there were different variants, so it could just be a different version.
