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.

Klon Centaur - Bare Bones

This layout is the legendary Klon Centaur, but without the charge pump. The charge pump is present in the original to keep the 2nd opamp from clipping. But since there are diodes before signal even reaches that IC, it may not matter. Check out this thread on FSB for more info and schematic. Without the charge pump, the circuit was much easier to layout for a smaller footprint. Still a fairly large board, but should still fit in a 1590B.


  1. the two 2.2nFs in parallel on the schematic should be a 4.7nF, not a 1nF...

    you might want to check the direction of the gain pot(s) as well

  2. Verified. I just finished it. Wester was right in his observations, the gain is backward and the 1nf should be a 4.7. With those alterations done it works perfectly and sounds brilliant. This one certainly will be boxed!

  3. Did you get into any problems with the missing charge pump / Headroom?

  4. Works ok, but compared to other klon clone (the one with true bypass wiring) this has got much lower amount of gain and overall volume.
