Dimarzio Custom Taper Potentiometer 500K EP1201 

Standard guitar pots limit your musical expression, only starting to deliver sound at about “3” on the dial and then never getting much louder above “7”. DiMarzio’s custom taper pot is made to solve that problem by precisely delivering the same ratio of signal-to-turn as an actual 10-position actuator. This provides players with audiophile-like control over dramatic volume swells and signal gain, so you can truly use the guitar’s total range. And don’t worry about wearing these out — each pot is rated to 10,000 cycles at 2,000 cycles per hour and is individually tested by DiMarzio to meet our rigid standards.
