As electronics tinkerers, we all use potentiometers, or "pots" for short. We count on them to control all our musical gear, and quite often get frustrated by their limitations. As in all relationships, a little understanding goes a long way. Let's take a look at how pots work so we can use them better.

Back in the dim reaches of electronic prehistory when electricity, let alone electronics, was poorly understood , a number of researchers were trying to figure out how this mysterious force worked. They had no meters, no oscilloscopes, not even very good batteries, and had to literally make their own parts to get anything electrical to work. In this era, a fellow named Ohm settled a controversy...
