CTS pots have long been the first choice in American guitars.
CTS precision audio taper gives you smoother and more accurate response than you'll get with economy pots. Crank your guitar up to 10 and the volume swells all the way—no abrupt flattening to choke your playing style.
Lutner's catalog contains the most popular CTS potentiometers of logarithmic and linear characteristics, with resistances of 250 and 500 kOhm.
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.
