CTS 500K-500K Concentric Solid Shaft Potentiometer - Audio Taper

CTS stacked concentric audio pot, intended for pickguard mounting. 500K/500K

This concentric pot gives you two controls in the space of one. An example of its use would be as the volume control in a two-humbucker guitar, where you would have independent control of each pickup, but using only one control location.

Audio Taper Pots give you a more perceivable change in sound over the course of a full turn of your guitar knob. A lot of guitarists prefer having a wider spectrum of control over their volume and tone knobs as it can be more useful in a live scenario. An Audio Taper Pot gives you more dynamic control for volume swells, and lets you roll off your volume knob to get a cleaner guitar tone with more precision than a Linear Pot.

Pot is 1 15/16 inches total height. Distance from bottom of pot to the bottom of the threaded portion is 7/8 inch.
Top knob diameter - 3/16 inch, 4.77 mm
Bottom knob diameter .265 inch, 6.75 mm.
