Add a switch without adding a hole. Sized to fit more guitars.On these top quality CTS control pots, the switch contacts are on the side, not the back. This makes them shorter, so they'll fit most guitars without routing—only 1 cavity depth is needed.The double-pole double-throw switch adds lots of wiring options. Pull the knob to coil-cut a humbucker, switch a pickup in/out, or control anything: the switch is electrically separate from the control pot.CTS pots have long been the first choice in American guitars. CTS worked with our team to create these unique control pots. In addition to their space-saving size, they feature a longer-life brass shaft and tighter ±10% resistance tolerance compared to CTS products offered elsewhere.Their precision audio taper gives smoother, more accurate response than you'll get with economy pots. The volume swells evenly from 0 to 10, with no abrupt changes.Each CTS pot includes a flat washer, lock washer, and two hex mounting nuts for custom height adjustment on a pickguard or control plate.Solid shaft potsShaft diameter: 1/4 (6.35mm)Thread: 3/8 x 32Threaded portion height: 3/8 (9.52mm)Required mounting hole diameter: 3/8 (9.52mm)Required cavity depth: 1 (25.4mm)Which pot value should you choose?500K pots are standard controls for humbuckers, and 250Ks are usually used for single-coil pickups. A 250K gives a slightly warmer tone than a 500K, and bleeds off (attenuates) some of the high frequencies to ground.
