So far, I have played both 509's and 513's with maple necks and without and a 305 with a maple neck. The 509 wouldn't have been as dark as the 513 in any case, and it has a subtly different voice than any of those three. The 509 pick up sounds more like it was wound with the wire used on 5708's, clearer and more articulate. The bridge also has more of a growl and a bit of a twang to it. I will be interested to hear how these 509 wood library run guitars sound with maple necks and swamp ash bodies.
