Fender 0990847000 Dual 500K/250K Split-Shaft Potentiometer

Strengths

When repairing the pickup controls on a compatible Fender guitar, this dual potentiometer brings 500K and 250K sound adjustment together in one component. Its dual-control design is intended to let you manage a single-coil and pickup control at the same time, making it a focused replacement for guitar setups that use this arrangement.

The split shaft and customized taper are designed for pickup and single-coil applications. For American Fender guitars equipped with Shawbucker pickups, this potentiometer is a specified option, the 500K/250K values also make its configuration easy to identify when matching a part to a repair.

Key features

This is a dual potentiometer with two sound-adjustment functions, rather than a single-value control. The 500K/250K combination supports the stated pickup-control application, while the split shaft identifies the shaft style for the installation. Its customized taper is intended for pickups and single-coil tapers, connecting the component’s design to the guitar-control task it is made for.

In practice, that means the part is suited to a repair where both control functions are required together. A single-value potentiometer may be the right approach for a different circuit, this dual-value model is the relevant choice when the existing setup calls for the documented 500K/250K arrangement. It is used on American Fender guitars with Shawbucker pickups, so that application is a useful reference when selecting a replacement.

The component is made from stainless steel and weighs 30 g. Its compact dimensions are 12.7 x 15.2 x 2.5 centimetres, useful details to keep in mind when identifying the part for a guitar-electronics repair.

Tips for day-to-day use

Before beginning a repair, compare the guitar’s control layout and the potentiometer values required by the circuit with this dual 500K/250K configuration. The split shaft is another useful identifying detail when matching the replacement to the part being changed. For the stated Fender application, check that the guitar is an American Fender model equipped with Shawbucker pickups. This keeps the selection focused on the intended setup and helps avoid treating a dual potentiometer as a direct substitute for every single-control part.
