The Fender Deluxe Jazz Bass Upper Concentric Knob is designed for bassists who need a straightforward accurate replacement for a missing or worn stacked control knob. It gives you a tidy way to restore the feel of your Jazz Bass especially if you rely on fast tweaks during rehearsals or gigs. The black plastic build keeps things lightweight and the white indicator line helps you see your settings at a glance — handy on darker stages or in busy practice rooms. Because its built for 1/4" solid shaft potentiometers it fits neatly onto the upper section of a stacked pot offering a secure feel once paired with your own set screw. You can drop it straight onto American Deluxe and Deluxe Series Jazz Bass models making it an easy fix when you just want your controls to behave as they should. Its a simple part but it keeps your bass working smoothly.
