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.

Apocalypse Audio Green Bomb Fuzz

For Fuzz Friday, here's a cool variation on the Fuzzrite circuit by Apocalypse Audio. It takes the classic Fuzzrite, adds some extra gain, and a pretty clever tone control. More info and the schematic can be found here.


  1. Verified!
    Great fuzz. It worked the first, made me remember immediately "satisfation"
    I did not have BC108B, I used 109B and C (300 and 500HFE), I also tested with 238B, 239C with good results.
    Thanks for the great layouts!

  2. Nice one ! It works, i used a 2N3904 and a 25088, it sounds great.

  3. The 100nF in H2 is the input capacitor, right ? It cuts out a lot of bass, which is pleasing, but i wish i could make a switch with a bass boost.
    Which value whould i choose to allow more bass passing through ?

    1. That is the input cap, yes. Try a 470nF or even a 1uF for more bass. Though the other cap values in this are pretty small as well and you'll probably need to tweak them as well.
