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.

D*A*M Drag'n'Fly

For #FuzzFriday, here's another D*A*M Fuzz Face variant, the Drag'n'Fly. This one is a silicon/germanium hybrid, using a BC337 silicon transistor for Q1 and a CV7112 germanium transistor for Q2 (but feel free to experiment with other transistors). I've laid this out for board mounted pots and the enclosure drilling template can be found here.


  1. Hello I am in Brazil and not found the Q2 CV7112 , what the best replacement ?

    1. The CV7112 is the same as the OC140. Really, any NPN germanium should work if it's around 100 hfe. Socket and experiment.

  2. Is this verified? And may i ask if the escobedo punch in the face layout is verified too, thanks man! Love all your stuff.

  3. verified! Used 2n5088 & MP38a, working!
