I'm going to use the push/pull on the tone control to allow full single coil operation. When the tone is pushed in, the pickups will operate like any other Uvi. When the tone is pulled out, the bridge and neck humbuckers will essentially become single coil pickups, which will make the Uvi work much like a strat with its three single coil pickups.
On another note, does anyone have info on the JS series (since you brought it up) whether the push/pull is actually for a
coil tap or really for a
coil split?
