I own two Dingwall Super Ps with Maple necks and one Dingwall Super P with an all wenge neck/board - in all honesty I’d advise not to think about any arguable differences in tone and instead concentrate on the look & feel of the wenge as the primary factors. Wenge feels lovely in the hand, with a more “natural” feel due to having a coarser, more open grain than maple. Basically, while maple necks feel totally smooth, wenge has a much more apparent grain to the touch, which is nice.
If you were to string all of my Super Ps with the same strings, then blindfold me and have someone play them each one by one, I’m certain I would fail to correctly guess which was which.
