Crafted to match the feel of original 1950s pots, this RetroSpec Custom potentiometer delivers the control and reliability a proper Les Paul restoration or upgrade deserves. Built to vintage-correct specification, with the characteristics that set 1950s Gibson electronics apart.
These aren't off-the-shelf pots. They're made to RetroSpec's own custom specification — the details we know matter from working on real vintage instruments. Each one is built with a solid brass thread and shaft for durability, a tight tolerance of ±9% for consistent, predictable response, and a resistance rated 10% over standard — 550K — for the fuller, more open top end that vintage-correct wiring is known for.
This is more than just a pot — it's the tone-correct component that brings your Les Paul closer to true vintage spec.
Available in short-shaft for Historic/Reissue models and long-shaft for standard models — sold individually.
