HSH Non-Believer (Silver Sky)

The only way to make the guitar better is to wire it HHH. Good ol’ Triple H! That should be your next project.

Single coils suck.
I'd like to see someone make a humbucker out of two Silver Sky pickups.
You could do it. You'd need a middle pickup that's reverse polarity. A typical Silver Sky middle pickup.

Wire it in series (not parallel) with either the neck or bridge pickup.

Not sure if the black and white wires would have to be reversed on one pickup or not.

If it doesn't work the first time then reverse them.
