This Panel Mount 10K Dual Log Potentiometer is a dual-ganged potentiometer that will satisfy all your stereo-signal needs. Instead of just one potentiometer, you actually get two separate pots, 'ganged' together. Turning the grippy shaft twists both standard logarithmic-taper 10Kohm potentiometers. It's smooth and easy to turn, but not so loose that it will shift on its own. They also offer this potentiometer in a singular configuration.

Potentiometers, or "pots" to electronics enthusiasts, are differentiated by how quickly their resistance changes. In linear pots, the amount of resistance changes in a direct pattern. If you turn or slide it halfway, its resistance will be halfway between its minimum and maximum settings. That's ideal for controlling lights or a fan, but not necessarily for audio controls. Volume controls have to cater to the human ear, which isn't linear. Instead, logarithmic pots like this one increase their resistance on a curve. At the halfway point volume will still be moderate, but it will increase sharply as you keep turning up the volume. This corresponds to how the human ear hears. Using a log pot therefore gives the effect that a setting of full volume on the control sounds twice as loud as a setting of half volume. A linear pot used as a volume control would give large apparent changes in loudness at low volume settings, with little apparent change over the rest of the control´s range.

Unlike some of Adafruit's other potentiometers, this one is not breadboard-friendly. The pins are about 0.2" apart so it will fit into a breadboard, but the two rows are close together so you'd short the two halves. Thus, we suggest soldering wires to the pins as necessary, using these in a perf-board that doesn't have the rows connected, or designing a custom PCB.

Once you're done prototyping, you can drill a hole into your project box and mount the potentiometer using the included washer and hex nut. Adafruit have got plenty of matching T18-splined knobs that you can pair up.
