R.G.	Re: Colorsound Wah info/schematic? It was two transistors, but one was an emitter follower buffer. Otherwise it was very like the CS one. A high gain transistor stage with twin-tee feedback, and some way of adusting the gain so it didn't oscillate on its own. The resistor at the bottom of the 2-capacitor T was variable for moving the resonance. This was from the pages of Poptronics, back when dinosaurs roamed the earth.
