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.

Zvex Box of Rock

This layout is for the distortion side of the Box of Rock. The Boost side is just a SHO. I've laid this effect out for top mounted pots like in my other Zvex layouts and should fit vertically in a 1590B. Pots are 1.1 inches (28mm) apart.

Board dimensions: 3.2 x 1 in. or 81.3 x 25.4 mm

  1. Can anyone confirm if this layout works?
    I've build it, but so far I have not gotten it to work

    1. Someone has built it successfully, so it should work. Have you taken an audio probe to it?

  2. Verified (again :-) )
    The most dynamic and clean distortion I've ever built.
    Thanks!

  3. An observation. In some schemes I have seen that the 56nf capacitor is 1uf.
    What is the reason for this difference?
    Thank you

    1. It's a coupling cap: not a big deal.
      I guess the difference between them aren't too much noticiable.
      Maybe less muddy/a bit more bright with the 56nf?
