An idea I have had and finally got around to trying. Each thumb position is linked to several finger touch points (thumb and one of the finger points to make a noise). Uses a stereo boom box for the bent circuit parts. Overall I like it though I want to do one that will use touch controld on one side of the circuit and knobs to control the other side.
To Main Menue page:
1: 1/4 inch output jack and knob to control strength of output signal.
2: Internal circuit board balence, tone and volumn controls (as I recall though not completely sure....).
3: On/Off switch (note the light in bottom center so I might notice that I had left it on......).
Green Circled points and knob are one set of thumb and finger contact points with associated power control and the pink are the other.
