Did you use Joints, nails, glue or screws to fit them together? Myself, I'd always use classic wood joins, dovetail and the like, because you want to ensure that the resonance frequencies of the wood you've chosen match the soundscape you are wanting to create (what wood did you use? I like a dark mahogany myself, for those rich smooth bass sounds, much better than pine or some other softwood, but if you're making tops and want the treble, that's often the best option), and not be disrupted by foreign materials, especially metals which being electrically conductive can introduce all sorts of instabilities into your system.
All platinum wiring and soldering throughout yeah? sweet. I'll have to come round sometime and suggest some ridiculous piece of equipment/accessory you need to improve your sound in order to assert my dominance over your audio skillz.
