  2. The ground jumper from k11-p11 is grounding the emitter vref instead of being connected to the ground track at j11

    1. Hmm, not sure I understand. The jumper between emitter of Q4 and pin 5 is Vref (k11-p11). And the emitter is connected to ground through 10k?

  3. I think this layout is like 95% verified. It's working fine except the Rip pot isn't functioning quite like the demo vids I watched. But it's possible it's my janky 3904s. I've got some coming in next week from a good supplier so I'll throw 'em in the sockets and report back if that fixes it. thanks for the layout!

  4. Managed to breadboard this. Seems the Rip has a narrow interval where it does something. Too high and it gates into silence, too low and it all gets quite clean. The Fuzz knob does not do very much unless maxed out.
    On SC very narrow, humbuckers better, but this might not be for me.
    Or might I have done something wrong to not get more fuzzy tones out of it.

  5. The link for the schematic leads to a diagram for "paper scratcher fuzz." Is the ripped speaker a modded version of the paper scratcher?

  6. It's a version of the EH circuit. The circuit itself can't be copyrighted but the name of the pedal is protected legally.
