This is the type of project I totally geek out with. I LOVE wiring modifications on guitars. I often wonder why coil tapping isn’t a standard on every guitar. You have a guitar humbucker that can always single out one or the other side of it’s coil, why not add a push-pull pot and give the guitar an extension of it’s tonal range?

Ah, let me back up a few steps here. What is this coil-tapping and phase reversal you ask? A humbucker is a dual coil guitar pickup. It’s essentially two, single-coil pickups wired together to cancel that age-old wiring hum. By wiring a pickup to a switch, you can single out either side of the humbucker’s coil and have the sound of a single-coil pickup. With 2 humbuckers, you’ve now doubled your guitars potential sound!

Phase-reversing involves flipping a humbucker’s magnet polarity. The effect it gives is a thinner, nasally, quackier sound. It seems to accent different overtones when switched on and even makes it easier to play harmonics… though that’s more of an opinion. Phase-reversing was used a lot in the 1970’s and 80’s. The effect is liked by a lot of blues players for lead tones… though certainly not limited by it.

So first off, the guitar’s owner provided a set of DiMarzio humbuckers which first needed to be installed and two holes needed to be drilled for the mini-switches. The push-pull potentiometer was used for the coil-tapping switch, and the on/on mini-toggle for the phase-reversal. After an hour or so of meticulous soldering, the electronics were ready and working.

Something interesting, which I was unaware upon the start of this job is the phase-reversal switch also acts as a coil selector when the humbucker has been split. In other words, you can select which side of the humbucker you single-out when the coil-tap is enabled. With these two switches installed, this guitar’s tonal range increased exponentially from 3 tones, to 15!

After all this funness with wiring, the guitar was set up to C standard. The string slots of the nut all needed filing to fit the new, larger strings. Lastly, the guitar was strung up and this job was done!
