CTS Push Pull Pot Wiring

Here is our guide to working with CTS push pull pots. Adding a push pull pot to your guitar opens up a new world of potential switching options and in this guide we cover some basic wiring mods you can try out and some easy to read diagrams (specifically covering CTS push pull pots).

CTS push pull pots are slightly different to your typical push pull pot. Whilst being identical electronically, the DPDT solder points are in the format of a printed circuit board on the side, rather than on top as with a classic push pull pot.

This layout confuses many at first, but they are actually very simple to use and a superior conponent.

Instead of soldering to the solder points on a classic layout, simply solder to the lettered/numbered solder points on the PCB, C1, C2, 1,2,3,4.


How Do Push Pull Pots Work?

how push pull pots work

Push pull pots are essentially DPDT (double pole double throw) switches. So looking at the 6 solder terminals, C1 + C2 (C being "common") are always connected. When the push pull is in the down position, terminals 2 and 4 are also connected. When the switch is in the up position, terminals 1 and 3 are active. while 2 and 4 are switched off. This gives many options with guitar wiring!

Below you'll find a range of wiring diagrams covering the most common push pull pot wiring mods for your setup, including coil splitting, series/parallel switch wiring and even how to use a push pull pot to act as both a volume and a tone control. To keep things simple and in the common interest, where applicable, the diagrams use Gibson humbucker 4 conductor wire colour codes.

Coil Splitting

Coil splitting is an extremely common mod which effectively shunts one coil to ground when the push pull pot is in the up position. You can read a lot more on coil splitting and how it works by reading our guide here. Your pickups need to be 4 conductor hook up wire and you will need to identify the respective start and finish wires of each coil.

Series/Parallel

This mod allows you switch your humbucker from series to parallel and works really well with higher output humbuckers. Pickups that are wired in series will have a higher output as well as a fuller tone, on the other hand pickups wired in parallel will have a brighter sound but less output, giving you the best of both worlds. You can get some of that "quacky" tone and it really opens up the potential of your pickup!

Volume/Tone Convert Mod

This setup allows you to use a single control as both a volume control and a tone control. This is extremely efficient if you only play with one control knob or are confined for space.

One Pot, Two Tone Capacitors

The below diagram shows you how to use a push pull pot to select between two different capacitor values whilst playing. For this be effective, it's best to choose a wide range between the two values...but obviously you can experiment and use whatever you prefer!

These are just a handful of wiring mods you can do using push pull pots - the possibilities are nearly endless! You can add just one push pull pot to your guitar or bass to give it an extra dimension, or you can go full throttle and stick 4 push pull pots in a Les Paul (not for the faint hearted!)
