Q: How do the push/pull pots on this harness expand my tonal options?

The push/pull pots on this harness provide advanced switching capabilities. They allow you to coil-split your humbuckers for single-coil sounds, reverse the phase of a pickup for unique out-of-phase tones, or wire pickups in series/parallel for different output and character. These functions combine to create the "twenty-one tone" versatility.

This product doesn't have any review media yet!

It functioned perfectly but not right out of the box. It really is a huge improvement from the factory Epiphone electronics with its extra tonal possibilities and upgraded caps. However, you gotta really have a lot of patience and resilience to install this. The product looks exactly like the photo when its delivered but the pic doesnt tell you how much "extra" wire is used to make it look no nice. The push pull pots just barely fit through the F hole and bridge pickup cavity openings and with all the thick semi rigid wire considerable stress is placed on connections as they're coaxed inside to their destinations. This resulted in several broken connectiions which of course you dont realize until everything is in place. After the third attempt, I replaced some of the factory wire with more flexible wire to finally get it in without a connection breaking a connection. Next time, I will just buy the components and build the harness myself.

I have a Sheraton, I thought with this harness I would be the tone KING! NOT!! If I turn down the volume below 8, I lose all ability to create tones bridge and neck. It goes dark and very muffled. Very disappointing.
