Product Overview

CTS 500K audio taper pro guitar pot with brass shaft. These are the highest grade pots available from CTS. Unlike most standard CTS pots that have pot metal threaded bushings and aluminum shafts, our CTS pots are custom made with solid brass shafts and brass threaded bushings that provide a super smooth feel with low noise operation and superior durability. Specifically designed for top performance in guitar volume and tone circuits. 3/8" threaded bushing for mounting through the top of the guitar.

  • Low capacitance heavy duty carbon resistive element provides noise-free audio and a long life.
  • Tight tolerance of +10%/-10% prevents tone loss from load mismatches and low pot values. (Standard pot values can vary by +/-20%!)
  • Solid brass shaft provides a smooth feel, noise free operation and longer service life than aluminum shafts.
  • Fine spline (USA) shaft for use as a direct upgrade/replacement in most American guitars.
  • Includes friction washer, top washer & mounting nut.

    CTS for semi-hollow wiring

    Posted by Sebastian on Jan 25th 2021

    I ordered a pair of these for a semi-hollow rewiring project and they worked great! The shaft length is enough to make it through that top layer of the guitar. Would definitely use these again because of the high quality and “feel” of the knob sweep

    CTS 500k Pots

    Posted by Keith B. Lyons on Aug 27th 2019

    I ordered several of these pots and I was pleasantly surprised that most of them were at or above 500k. I'm very particular about pot values and in a typical order I usually have to set aside or discard several pots that are below 475k. I know there is a +/- 10% tolerance with CTS pots, but they often fall short of that standard on the minus side. I don't know if it was the luck of the draw with this order, but only two of the pots were below 500k, but still above 475k. I'm pleased. I ordered several other parts and it's too time consuming to rate them all individually. But, I really appreciate being able to order parts specifically by brand name like Gotoh, AllParts, WD, Fender, etc.
