i was planning on doing the sunken body as you mentioned, the only concern i have is ensuring that the strip behind the truss rod is a nice tight fit, but using a "thicknesser" i have made (a router bolted onto some long pieces of steel running on brass rails that are paralell to the surface underneath) i should be able to get the right thickness, and then use small router bits for the corners of the truss rod slot, so that the radius can be sanded easily.
the laminate is 1pc of zebrawood in the middle ( 23 mm wide) 2 pieces of wenge either side of that (10mm wide each) and then 2 pieces (10mm again) of new guinea rosewood (i believe its refered to as narra in america). narra is also the wood for the wings as it will be a neck through.
ive decided, after getting alot of expensive wood for the neck (wenge and zebrano) and a cheap (but aparrently sounds very good) bodywood, ive decided its the way to go $$ wise, as the body takes up alot more wood, and getting an expensive body wood changes things alot. if i got maple for the centre strip, it would have saved about 7-8 $, but a more expensive body wood, would have been a fair bit extra. i realised that after getting the wood for my last build from a piece of walnut (which wasnt completely usable, so i got a discount already, but fine for a body and a little bit extra) i havent finished that build, but im going to get this one started as its for my girlfriend, who is singing in the band weve started a few months ago, but havent had much luck getting bass players that are easy to get along with, and are not too busy for a band. so my girlfriend will learn bass and make it a 3 piece, hence why i wanted to get this one stated so we dont have to borrow a bass for too long.
