RE: Pickguards, the jury is still deliberating, but in general I loathe them. Except possibly on an acoustic guitar. I like to choose pretty woods, and then show them off instead of hiding them behind plastic (and just no on the clear pickguards..) I might do a minimalist plate for the 4 knobs and 2 switches, as I am leaning toward the MusicMan control layout.
RE: Pickups, I am going to wait until the last possible moment to order these. If I had to do it today, I'd have to settle for a pair of BQLZR ceramic PU. I'm hoping to be able to pull some money together and grab the Seymour Duncan set with a preamp, and a second pickup for the neck. I'm thinking if I can get the SD PU, that I'd get 1 Alnico, and 1 Ceramic and figure out which one goes where (bridge vs neck) on the instrument. I'd like to wire them so that I have a 3 way switch on each pickup (Each coil separately, and then Humbucker in parallel) and a blend pot before the master volume, with a 3-way EQ. So there'd be 4 knobs (Blend, Vol (push/pull for the slap control of the SD), Bass/Treble, Mid) and 2 small switches (3 way On/Off/On?).
RE: Body, I think the shape is coming together nicely. The photo mashups that
@RichterScale and I did are very close to what this is going to look like. In fact, the lower bout on both the Rickenbacker and the MusicMan are so close, that I'm just mirroring the Rickenbacker lines from the CAD drawings. The current plan is to glue up the back out of 2 layers of 3/4" mahogany, and then top that with about 1/4" of the birds-eye maple.
I'm going to steal a trick I saw on a SBO thread to arch the back, where the sides of the neck blank was beveled to allow for the sides to flare back (as I want to do for contouring - a la Spector). So the 2 layers of mahogany and the core of the neck will have a nice bevel to them (about 3 degrees). Then I will have to machine the top back to flat for the top to go on. So my 2" thick body will likely wind up in the 1 1/4 - 1 3/8 range. I'll have to see how it goes, and make sure that the bevels don't make the center too thin! The top will be flat, so machining a recess for the controls makes sense to me, otherwise I'll need to route that before I glue the sides onto the body! I will also have to machine the arm bevel in once the mahogany is flattened, as I want that to be a clean break, and be fully topped with the birds-eye.
RE: Bindings. I am thinking that this will be my first bound guitar. (not that I'm not using a ton of other new techniques - what's one more!) and I'm leaning towards white/abalone (plastic)/white, although white/abalone/black has it's appeal too. Also looking at abalone for the fretboard inlays.
