Ilitch noise cancelling system.

The BluesHawk uses a similar system. The "Dummy Coil" in the back of the guitar between the pickups provide hum cancelling when single pickups are selected. The Gibson BluesHawk has Blues 90 pickups and the Epiphone Blueshawk has standard P90's, both of these have their neck pickup in opposite polarity (the bobbin and magnets are reversed) so when selector switch is in mid position the opposite polarity of the pickups provide hum canceling. Most other manufacturers are using this reverse polarity setup with P90's but Gibson doesn't normally do this, but if you use a Strat on position 2 or 4 this is what it is doing with the center pickup in reverse polarity.

You can test your P90s simply by placing a compass next to them, if opposite the compass will swing 180° between pickups..

The ILITCH system looks like they have taken it it bit farther than Gibson did, maybe they got right..

Cavity Noise Canceling Systems CVNCS JR

Gibson Les Paul style guitars that have a back control cavity and one or two single coil pickups can be retrofitted with a CVNCS JR
The CVNCS JR replaces the control cavity cover and has been designed to fit the original hole pattern, making the installation 100% non invasive.
Note: All single coil pickups MUST be same polarity same winding direction (No RWRP)
