Hi Twobeers and welcome. Going to be a very flexible guitar if you can get it all working. I find a lot of those 21 different pickup combinations aren't that useful or different sounding. I use the coil taps and occasionally the two pickups out-of-phase for some Peter Green numbers.

Just be aware that Lace recommend 250k pots for their Alumitone Humbuckers, so you'll need to make your own loom up rather than buy a ready-made one which will almost certainly have 500k pots in.

Good luck with your build!
