Skreddy Top Fuel

For Fuzz Friday, here's another fantastic Big Muff variation from Skreddy–the Top Fuel. It replaces the input stage with a MOSFET-based stage, and uses an interesting diode array for the 2 clipping stages. There's also a fabricated version of this layout in the store here.

  1. I have been trying out the DIYLC layout software (on a Mac)... How do you get the ground plane to give the clearance around the pads and traces? Or are you using something different for the PCB etching layout?

    1. I'm pretty sure both are completed using an image editing application :)

    2. I do the brunt of the layout in DIYLC, but the ground pour I add in Photoshop.

    3. and here I was searching for a long awaited ground plane tool in DIYLC... darn-di-darn-darn-darn!

  2. Verified! I didn't have a 2n cap so I used 2.2, I might try 1.8, but I think it has enough brightness. I'll have to try it through my main amp to really see. It's got that mosfet sorta squish in the tone. I'm digging this thing.

  3. This looks really good! It's the newer version. Any substitutes for the BC239?

    1. Pretty much any typical big muff transistor will work there–MPSA18, 2N5089, BC549/550, etc.
