Mini-taur? Shrinking the footprint of a 1:1 Klon Centaur Circuit

Updated: Feb 10

A lot of the circuit boards I've been designing lately have been to address my own needs. One of those is a smaller footprint Klon Centaur pedal. Yes, I could buy one of the thousands available however, I already had the schematic drawn for the BFK so it was easy to create my own 125B-sized pedal by arranging the parts differently. Proudly making things is fun!


My goal with creating a new circuit board was:

  • 1:1 Signal of the original Centaur.

  • Needs to comfortably fit inside a 125B enclosure.

  • Thick signal and power traces.

  • Parts selection for both 1:1 original parts as well as room for more exotic parts selections.

  • Make the circuit board BLACK.

  • Improve the grounding and overall manufacturing utilizing 2-layer 1.6mm boards.

Above is an example of using the same parts selection as the original Centaur. Mainly the Panasonic caps, resistor type, op amps, etc.
