DiMarzio EP1201L 500K Long Thread 18mm Custom Taper Potentiometer

Take full control of your guitar’s dynamics with the DiMarzio EP1201L 500K Long Thread Potentiometer, engineered for precision and expressive range far beyond what standard guitar pots can deliver.

Most stock potentiometers don’t provide a smooth volume curve—sound often only begins around “3” on the dial, and stops changing by “7.” DiMarzio's custom taper design fixes that with a true 10-position signal-to-turn ratio. That means smooth, predictable swells, expressive fade-ins, and full-spectrum volume control, just like turning a high-fidelity audio knob.

Perfect for guitarists who ride the volume knob or seek more expressive dynamic shaping, this long shaft version (18mm bushing) is ideal for carved-top guitars like Les Paul® models and other instruments requiring deeper control cavity reach. Built for reliability, each unit is tested to withstand 10,000+ cycles at 2,000 cycles per hour, ensuring it performs consistently gig after gig.
