Ibanez Fuzz No. 83




And a modified layout with a few tone controls in place of the tone switch.
This one is verified as well.

  1. Have you made one of these? If so, how's the volume? Guess I should just build it and see.

    1. Yes, I have. Sounds pretty good but with a boost up front it really shines, it is almost like an superfuzz without the octaves. Output level is definitely loud enough.

      Did some mods for it for some more versitality....omitted the switch and added a Treble and Mid control. If I can find the layout for it I can post it if you want to.

  2. Yes! That'd be great. I'll build it as soon as I get some more 2sk30's. Checked my stash and I only had one left. Thanks dude!

    1. The original had fuzz 1 to ground so the sound was muted totally when fully anti clockwise. I just added a 2,2k liminting resistor to solve that issue, Big Muff has the Sustain wired the same for example. Row H and bottom row is grounded (except for 2,2k/fuzz 1 junction) and so is the emitter of Q2.

      it shouldn't be quiet at all, it must be an issue in your build. Which transistor do you use?

  4. Gotcha. That made sense after I looked at it again. I used a 5088. I'm sure something is amiss on my end.

  5. It's looking like I have bad 2sk30's. They're from Small Bear too which is unusual. I found one from Tayda and put it in Q3 and it woke it up. Plenty of volume now just not very fuzzy. Gonna have to order more.

    1. Yeah, I've been through the same thing....Tayda 2sk30's works great but the ones I had from Banzai were junk....

      You could do some leg twisting to try other J FETs in the meantime.
