WD Music Products® developed this high-quality potentiometer with CTS® to offer you exceptional performance in electronics for your instrument. These vintage look-a-like potentiometers (with indented can) are NOT the same CTS pots that other companies stock and sell. These are developed using ±10% tolerances. This ensures not only optimum performance, compared to many others using 20% or 30% tolerances, but also good tone from your pickups. We’ve also added brass components and a high quality wiper versus what comes standard on most run of the mill potentimeters to ensure long life, quality and consistent performance.
