I've owned and played basses with maple necks that I've loved, and others I've hated-
I've owned and played basses with wenge neck that I've loved, and again others I've hated
I'm certain in myself that the wood does affect tone, but the variation between seemingly identical instruments can be so profound it's almost impossible to say without doubt which I prefer.
I've disliked most wenge necked warwicks I've played- and swiftly connected the main outstanding feature (the wenge neck) with that dislike.
Yet my old Sei original 5 was made almost entirely of the stuff and it was fantastic.
Like CK said, it's all a balancing act.
I try not to judge a bass by the wood it's made of anymore- if it sounds good and feels good- it is good, whether it's made of ash or mdf.
