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.

EarthQuaker Devices Talons

A while ago I laid this out for board mount 9mm pots at the request of someone on FSB. Always intended to modify that original layout for use with more common 16mm pots. Turns out it was easier to just lay it out fresh. Anyway, the Talons is a very versatile OD with an active 3-band EQ, and can run off +9v or +18v power supplies.


  1. hey, just noticed that the pull down resistor on the input is 3k3 ohm, probs a typo with 3M3?
    Great work as always for the layout!

  2. Do you have a schematic for this per chance?

  3. ..and even in a smaller board.. you're a genius!
    May I say "an improved Guv'nor"?

    1. You could. Though the 2 are pretty different... Soft clipping in the Talons vs hard in the Guv'nor, different EQ sections...

  4. Built. I also built the 9mm one a year ago. It sounds great with a powerful EQ. Now to build an 18v!
