I can sympathise with k.dee. Ive heard the nailbomb be loose and grating and tight and grinding in different guitars. I hated it for quite a while, and now I like the NB and LOVE the c-bomb *in the right guitar*.
I currently have c-bombs in a jackson DX1 and the Legra MDV602. There they're both tight, punchy, growly, clear and precise but not with the really sharp in your face high end of the MM (which it has to be noted I havent had in the same guitars...quite; I had a 23k double screw pole MM in the jackson which is far from the same thing!).
Being that I havent had them in the same guitars, but I have had the c-bomb in guitars not a million miles from yours wood wise (maple neck and basswood, and mahogany with maple strips and swamp ash body) I predict a fairly hefty but overall balanced low end, more mids, that are quite even and more open, less sizzle in the top end, and a sweeter sound with a blunter more percussive attack in the top.
That said, the guitar that I first heard the NB in was a maple neck basswood body dean zx: acoustically thin and gutless compared to the identical wooded jackson (which is even FR to the ZX's TM to boot), and it sounded like pots and pans with no definition in the low end.
I've said it before, I'll say it again - BKs dont agree well with cr@p guitars. They agree very well indeed with good ones. Acoustically speaking that is. If you think its a good guitar, with decent resonance across its range, I believe thats what the NB (to a greater degree than other BKs, in my experience) needs and you should go for it.
