CTS potentiometers are high quality and renowned controls for guitar electronics. The 500K Ohms resistance gives a brighter tone and traditionally used for humbucking pickups and its linear taper traditionally used for tone pots. These have the standard shaft length (long shaft are available separately).

We supply these potentiometers in two versions, metric and imperial, the imperial version has a 9.5 mm diameter brass shaft with fine 24 spline mounting for control knobs and is most commonly used on USA made guitars (e.g. Gibson, Fender, PRS etc.) and is traditionally the standard version of a CTS pot, the metric version has an 8 mm diameter brass shaft with coarse 18 spline mounting commonly used on Alpha pots and guitars made in Japan and the far east (Epiphone, Squier, Ibanez, Schecter etc.) and allows you to upgrade more affordable guitars with CTS quality electronics. To use knobs with a set screw, simply line up the set screw with the split in the shaft and tighten the screw.
