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.

Basic Audio Scarab Deluxe

Happy Fuzz Friday! Revisiting one of the early layouts of the blog–John Lyon's Scarab Deluxe. Been meaning to draw it up with board mounted pots for a while. Ian Nelson sent me his version and with a little modification we can check that off the bucket list. Great sounding fuzz based on MicTester's Hot Silicon.

  3. I'm having the same problem, it seems that a 10k resistor is missing between the Q2 collector and Q3 base, and the 9V.

  4. OK! I already have sound (and quite high), the problem was even the lack of the resistance of 10k, but it seems that there is something else that is not well.
