4ms Fuzz Jade

Happy Fuzz Friday, everyone. Today's layout is a cool variation of the Fuzz Face circuit, but with the addition of a Big Muff tone stack and a gain recovery stage. There's also a Mud pot that starves Q3 for extra tweaking. Board mounted pots and 1590B friendly. Here's the schematic for reference.

    Sounds cool! Think this may be my next build when I'm done with whats on my table now.
    Any way you could work up the Mad Professor #1 pedal? I would love to have a crack at that one!

    Verified.

    The effect sounds more like a Fuzz Face than a Big Muff, but much more buzzy and gated.

    The Tone control loses a lot of volume in the middle position, so it may be worth trying other Big Muff tone stack values.

    Q3 gates and distorts rather than just compensating for the lossy tone stack.

    The Mud pot is too big. 5k pot will already starve Q3 enough that the effect volume will be below unity with the Gain and Volume controls maxed.
