If it's done right it shouldn't matter. Or does it? Looking back I realize that I have only "bonded" with flatsawn necks to the point that now I have the notion that they are superior to quartersawn. I can only imagine that the neck must flex slightly more with flatsawn (which gives the tone and feel I like). I think Mike Lull is a flatsawn fan too. Who else is of the mind that one is better than the other?
