Bourns® Model PDB183-GTR21 Guitar Potentiometer with Push-Pull Switch. Used for Split-Coil Pickup Switching Electric guitar manufacturing is a multi-billion dollar industry with major manufacturers established worldwide. From the introduction of the first mass-produced electric guitar in 1950, guitarists have been mesmerized with advances in technology and the wide array of after- market parts commercially available for guitar upgrades. Specialty products such as Bourns® Model PDB183-GTR21 Guitar Potentiometer with Push-Pull Switch allow the guitarist multiple functions utilizing a single control such as split-coil switching for humbucking (double-pole) pickups or stacked single-coil pickups, active electronics activation, and pickup phase switching. This application note addresses utilization of the PDB183-GTR21 to enable split-coil pickup switching in electric guitar humbucking pickups. Bourns® Model PDB183-GTR21 Guitar Potentiometer with Push-Pull Switch is designed to allow the guitarist switching capability and volume or tone controls with a single 18 mm package size potentiometer. The potentiometer is designed with a single shaft that is used to activate the Double-Pole, Double-Throw (DPDT) switch and to adjust the potentiometer. The DPDT switch can be wired for various switch functions.

No, this is a push-pull dual gang pot. Yes the two rows of terminals are doubles. Basically it can change two separate resistances at once or work in a stereo application.

We can verify that this can be used to change tone caps in a circuit, although we do not provide technical support. We advise you consult a tech to provide advice and suggestions for how one would wire this pot to achieve the desired results.

This potentiometer is DPDT but it is not concentric.

There are many different models of a Fender Precision bass, but this shouldn't have a problem fitting in any of them. There may be exceptions to this rule, and if you are still concerned about a proper fit, you can compare the measurements of your bass with those provided in the data sheet above.

Bourns does not provide a current rating for the switch. This is likely due to them being designed for guitars which typically use passive electronics.

Ordered this dual-ganged pot to modify a 2015 Marshall JVM 205C amplifier, adding a variable Negative Feedback control to effectively alter it's sound to allow the amp to be more flexible in it's use. After design, I soldered some other choice components on it and it worked as described the first time in the circuit. The pot is a tad scratchy, but works well enough to be a keeper.
