I see Digikey has pots for 79 cents, I think I'll get a few and try out a mod. My idea is to just replace R5 with a 2K pot and a 1K series resistor. That allows me to vary the gain from about 1:1 to 3:1. This also preserves the input signal monitoring indicators. What would be really cool is a graduated dial with the gain figures on it, but I think that's gilding the lily.
