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.

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.
