This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

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.

  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.
