Zexcoil pickups are my official pickups. I first tried them in early 2013, and quickly became an endorser. They are the best pickups I’ve played - not just for the hum-cancelling, but for their incredible tone as well.
Zexcoils are built like no other pickups. They use one coil per string, and are hum-canceling by design - without the use of dummy coils or other tone-sapping “tricks”.
Here's a list of all the places you can see this piece of gear in use.
