    1. I'll take a look at the schem tonight and see if there is a n error in the layout tonight.

    2. Compared it to the schematic and found some minor errors. First, simple remove ik reistor connecting to pin 6 of IC1. God knows why it is there. Also, connect switch 3 to the other side of 470 ohm reistor left to IC1. I've updated the layout and shifted a few things around but those fixes should hopefully fix your build.

    2. Awesome! Thanks for verifying. How do you like it? And how is it compared to a stock Rat?

    3. Tis awesome. More refined. Tbh it feels like its more choked gain wise, less fuzz definatly more od/distiortion cranked. The cut is nice, more usable than the rat personally, was dinding some nice low gain tones with a generous amount of cut.
      Gonna box this bad boy and box one for a mate who was enquiring not long ago.
      Your quantum mystic layout though. Thats my new heaven though. Goddamn.

    4. Ok, I think I will build it too then!

      Quantum Mystic is great but I highly recommend a simple buffer upfront since it squeals with all knobs dimed but thats the nature of the beast. I've talked to people that has a real one and it squeals too...

  6. Just build this sound amazing But question the drv knob does not kill distortion at unity any idea of what could be the problem ? over all sounds good
    Thank you

  7. So I compared this to schematic, drive 1 should go to 470ohm and 220nf to ground to cut distortion At unity

    Awesome job you guys

    Thank you again

  8. Built this out of curiosity more than anything else. I omitted the cut at S-9, to link pins 1 and 8 of IC3 for a MAX1044 instead of the Lt1054 as I didn’t have one on hand. Sounds cool through my little honeytone that I use to test circuits. It’s a slightly more open and less nasty sounding Rat style pedal I suppose. Dunno if such a thing is needed but it’s cool. Sounds like Josh Scott’s wet dream. Indie and compressed. That’s through a little plastic amp though. Thanks for the layout as per usch. Happy horrordays!

  9. Tried it into my Fender today. Mid pushed and cutting. It makes me struggle to find a warmer setting which isn’t really there. Sorta feels like a rat trying to be a klon or a ts. So maybe a rat for strat guys or Gibsons. A boost for guys who want a more asymmetrical fuzzy texture than what’s traditionally available. I like it. Not smitten though. Thanks again for the layout.

  10. Nope something was shorting a bit. It slays. Haha sorry for the bi-polar posting. Enthusiasm and lack of patience. Stuck it in an old Rat enclosure with a pink LED.
