Editorial Review SAVE WHEN YOU BUY A 4 PACK!Great price!Alpha potentiometers are among the world's most widely used guitar tone and volume controls. Each pot has an aluminum split shaft that fits a coarse-knurled (18-spline) knob.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.Shaft diameter: 6mm split shaft, coarse knurlingThread: M8 x 0.75Threaded portion height: 3/8" (9.52mm)Required mounting hole diameter: 5/16"(7.94mm)Alpha pots are audio taper with standard ±20% resistance tolerance. Each pot includes a flat washer, lock washer, and two hex mounting nuts for custom height adjustment on a pickguard or control plate.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 some of the high frequencies to ground. A 1-meg pot bleeds off even less than a 500K-try one if you want to hear your guitar "wide open."1-meg pots are also ideal for piezo pickups, as the ultra high impedance piezo element is more adversely effected by conventional, lower-value pots than magnetic pickups.25K pots are for controlling the volume or tone of active pickups, or for use after the preamp of a piezo-saddle transducer bridge.
