Audio Potentiometers for Guitar Wiring

Potentiometers (Pots) for audio are used to adjust tone and volume. Pots are resistors with three terminals and a sliding contact (the wiper) that creates an adjustable voltage divider. If only two terminals are used (one side and the wiper), it acts as a variable resistor or rheostat. Potentiometers are most commonly used as control devices, such as volume control on audio equipment. A potentiometer for Audio applications would feature very low to no introduced noise.
