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 Clean Octave Blend

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.


  1. Please check if Blend knob is connected properly

    1. It follows the lug numbering of the traced schematic.

  2. It works. But Octave pot works weird. It regulates well just in last 30% of turn but also makes the sound louder. perhaps should experiment with values and type of the pot.
