Got a request for this one for Fuzz Friday. Originals fetch crazy prices online. It's an octave fuzz with a clean blend. If you want a fabricated version of this, check out the Corn Cobb on the store.. Schematic over on FSB. Should squeeze nicely in a 1590B.
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.
