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.

I checked stock and they all had x2 washers and nuts on them, so if yours only came with one, you can contact our customer service department.

Lock washers work well to keep a potentiometer in place when installing them. The S-HLW38 fits the 3/8" bushings on these potentiometers.
