November Mod Of The Month: 2 Tone Caps, 1 Push Pull Pot

Happy November! This month, we’re talking about a really cool and simple Push Pull Modification that allows you to choose between two cap values for your guitar. This modification is great on a Strat or Telecaster, where you might have a Master Volume and a Blender Pot, but still want the capabilities of two Tone Caps.

This modification also is great for those who want to use our Magic Cap on the Bridge pickup. Simply pull up (or push down) to select the right tone cap that will work best for the pickup you’re playing on. The 2-Cap Push Pull mod is simple to do, and an easy way to get more versatility out of your guitar!

Here’s what you’ll need to perform the mod:

  1. 250K / 500K Push Pull Pot
  2. 2 Separate Tone Caps
  3. Cloth / Insulated Lead
  4. Soldering Pencil and Basic Soldering Skills

The Mod:

There are two different versions of this Mod. They will do the exact same thing. It all depends on your preference! See below:

How It Works: 

In order for a tone pot to work, you need an input to the pot (this can be through a wire, or a cap in traditional uses), and one of the legs to ground of the cap. This allows the high frequencies to be sent to ground, thus giving you a darker tone.

The Input comes from the switch or volume pot, depending on what setup you have. The signal enters the pot on Side 1, Lug B, and is either connected to A or C, depending on whether you have it pulled up or pushed down.

Pushing The Pot Down Will selected Cap 1. It will connect the input with C. The other side of the cap is connected either to F (Version 1) or ground (Version 2). Either way, one of the legs is the input, the other leg is the connection to ground. Likewise, pulling up on the switch will do the opposite.

Well, that’s it! Pretty easy, and it’s a very usable modification to your guitar. We hope you find it useful! Cheers!
