a couple magnet theory questions...

The neck angle has a lot to do with the bridge height. A steeper neck angle will allow you to get the action lower at the bridge.

If Gibson wasn't using a Tune-O-Matic they wouldn't need a steep neck angle.

Has anyone done any field modeling of mismatches between pole pieces and strings? I have an 8-string lap steel that was built with a Kent Armstrong 7 string pickup. It has a Strat-like arrangement with 7 Alnico 5 rods, 5 x 17 mm, the outer ones 60mm wide on centers. The 8 strings are evenly spaced, the outside ones 63.5mm apart at the pickup centerline. Obviously there's not going to be a string right over each pole, the mismatch being greatest at the center where there's a pole centered between two strings. I've not noticed any string volume mismatch, but I do think it sounds best with the pickup lowered way down, about 7.5mm below the strings. Nice clean sound there.

Me too! Seems like only Schaller's offering that possibility.

Carvin also offers it. They used to 4 but then figured it you really only need 3.
