These pots are manufactured by CTS specifically for RS Guitarworks who designed the potentiometers to their specs which exceed those of the CTS pots that have been the industry standard for over 40 years with Gibson®, Fender® etc.
The RS Guitarworks SuperPot™ is made with tolerances that are twice as tight as the normal CTS pots used in even the most expensive Strats® etc. The cheap aluminum shaft is replaced with brass for better durability, the target resistance was designated so that the value will never fall below 500k.
RS Guitarworks also specified CTS's old-school heavy carbon resistance path instead of the inferior silk-screening currently used by many other makers and more importantly they custom designed the taper specifically for electric guitar volume controls. The custom taper gives smooth even response throughout the range of motion. You will not experience any steep drop-offs or uneven taper.
RS Guitarworks Superpots use a retaining clip to secure the mechanism together instead of relying on the crimped back cup, this results in a far stronger assembly, easier to turn (lower torque) and even pressure on the carbon resistor.
Together these features represent what is without doubt the ultimate potentiometer for electric guitar applications. These new pots cover any guitar application where a 500k pot is suitable.
These potentiometers are designed specifically for volume controls. They are not suggested for use as tone controls, our CTS TVT pots are perfectly suited to that purpose.
Please Note: All guitars manufactured in Japan, China, Indonesia and Mexico use metric pots (6mm), and have metric sized holes drilled for the pots. All pots sold by RS Guitarworks use standard pots and hole diameters (3/8"). Therefore, holes in the guitar, plates and/or pickguards will need to be enlarged to 3/8" to fit properly. Also, metric knobs will not fit the RS pot shafts; most popular knobs are available on the store in new and aged versions.
