trem? if trem, i recommend something harder than basswood as its a soft wood and CAN make trem posts lean with time under string tension (yes, i know it can/does work and nearly every ibanez is basswood, but I've seen a number of them with ovaled post holes and tonewood does not exist so why chance it?). also, basswood dents easier yadda yadda. No trem? any wood you like the look of. solid paintjob? cheapest wood. Natural/trans finish? wood you like the look of. Long winded way of saying, don't pick your wood for tone. Enjoy the process!
