I can’t comment on all instruments, only my own. I have 3 US Precisions with maple fretboards and 2 US Precisions with rosewood fretboards, all the same series, with same pickups, same strings (of the same age & gauge) and all set up the same. The rosewood ones sound deeper, the maple ones more twangy. It was especially evident in band practice. Whether that’s the same with all of them I can’t say, only in relation to my 5. And as I’m getting another rosewood one next week I’ll find out if it’s 6 of the best!
