  1. Any idea what amp circuit that is? It looks too complex to be a Little Gem or Ruby circuit, and his seems to have some cool features I’ve not seen anywhere else.

  2. wow, I am honored to be featured here, thanks a bunch!

    The circuit is basically the little gem, but with the headphone jack interrupt between the output and the speaker, and the LED power indicator/strum power/ tuning light bridged between the pos lead of the 9v and the pos track on the circuitboard.

    I also use a stereo 1/4 input jack’s other channel to turn the unit on by passing the ground through it, and back to the battery.

    I’ll see about darwing up a diagram. I had no idea there would be interest in that.

    The rest of my projects are here at http://www.nonentity.com

    Thanks folks!
