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.

Prescription Electronics Depth Charge

Here's a sweet bass fuzz based on the Univox Super Fuzz for Fuzz Friday. Original units used 2N3707 transistors with BCE pinout, which I'm guessing most people don't have in their parts stash. So I laid it out for CBE transistors (2N5088s or BC549Cs should work just fine) and it will fit nicely in a 125B with top mounted jacks and the pots in the same orientation/positioning as the original. Schematic available over on FSB.

  1. I think the 120k resistor comes from gain 3, not gain 2.

  4. Q4 and Q5 are very confusing. You have Q4 as being CBE and Q5 is EBC. I'm sure it's just a typo.
