You know, I think you've got me there. From what I hear the answer to the first is 'yes'. The answer to the second is... I think I have, the problem is it feels like the tail wagging the dog when I put it like that. I like the way they (Painkillers) sound... Hmm... More to think about... :)
yeah, i mean i dunno, it's up to you and all that, but to me at least, basswood is a bit more of a "jack of all trades, master of none" than things like mahogany and alder etc.. don't get me wrong, basswood's strength is the versatility, but that means for any given tone (apart from maybe 80's melodic shred like vai or satch), in my opinion at least, there's a better option out there... though basswood will "do" alder better than mahogany will, and vice versa.
i think i'm rambling a bit now, lol. EDIT: what i mean is, i'd buy the guitar you like best, and suit the pickups to that... tim does plenty of pickups that are aimed at mahogany, etc....
best if you can try them both (or all 3, including the x50pro)... only you'll know which you like best...
