does spector offer any other fingerboards besides rosewood (and, I'm assuming, ebony on fretlesses)? i think i thought i saw a maple fretboard on a us one, but it may not have been. also, what are some generalities you know of about purpleheart fretboards? is it almost identical to rosewood tonally? recently, i played a roscoe bass w/ purpleheart neck and another roscoe w/ph neck, and at least ph looks cool, really different.
