Timbre generator

PCBs - US$18
panels - US$20
assembled - US$160

This is basically a clone of the Buchla timbre found in the Easel. I have added a simple tri2sine converter input, along with the regular input, and buffered output. The panel looks dark blue when mounted in a case.

The only changes to the original version are to fit the signal levels to Eurorack standard. The circuit will deliver some noise when there is no input signal so it is best to patch it directly to a VCO or patch a VCA downstream. The original Buchla Timbre was the waveshaping section of a VCO so there was always an input signal.

Nov 2017 update - The current panel is white/gold. there is also a smd dual Timbre available.


  1. Question: How difficult is this to put together? Is there any soldering involved, or what?

    1. Yes lots of soldering, I only supply the bare PCB and panel. You have to buy the compnents, build it and get it working. Not suitable for beginners!
      I also sell these fully assembled and ready to use, USD160, shipping with tracking & signed delivery is USD20 per order

  2. what´s the depth of the timbre?

  3. hi is there a component list by Mouser or other ?

  4. Someone put this one on muffs, I haven't checked it -

    the build guide with BOM is here -

  5. Also feel free to join the NLC builders guild on FB, good place to ask questions -

  6. Hi, do you think it would work to replace the resistors with SMD ones, by soldering them over the holes?

  7. Hi! I've mixed up polarity and "something" was burned. Something is on pic which component should I change?

    thanks a lot!

  8. Probably one of the 10R resistors needs to be replaced. depending how quickly it was turned off the chips may or may not have fried too. Please join the NLC Builders Guild on FB for trouble-shooting help -
