Universal Expression Pedal?
« on: February 19, 2006, 09:22:52 PM »
I have been trying to think of a way to build a universal expression pedal. The concept would be that you would have a pot that was for example 0-100k ohm across the full range of the expression pedal treadle, but that this would result in reading either 0-10k ohm at the terminal or 0-100k ohm at the terminal. You could then have a switch to switch between range A or range B for pedal A or pedal B. I have seen something called digital potentiometer control, but I'm not sure if this is overkill.
