  1. Very cool, thanks! I'd LOVE to see the Impossible Colors pop up here, although I'm not sure if it's been traced... Bosstone-based I think. Fingers crossed!

  2. Hi, you can also tag this one, layout is perfect!

    Not much too say, its a hyperfuzz with a couple of nice tricks. Sounds heavy, thick and brutal, as expected.
    I tried some small adaptations (22k instead of 27k in rectifier), A5k for mid scoop, Si diodes instead of led clippers, and used mpsa42 (matched Q2 and Q3).

    While I have my share of super/hyper fuzzes, I think the clean blend in this one will justify boxing it. Even on guitar, it is really useful, and I'm having lots of fun blending other dirt with it :)

    Thanks!
