I have two Axis Super Sports, both hardtail, one with humbuckers and one with P90s. The necks are great, they seem unusual at first but that soon passes. I disagree with David .. I find both to be lacking in power / output.
One thing about Musicman guitars, they are not made to be easily modified, even adjusting pickup height on both is awkward ... the humbuckers are mounted to the body so they can not be lowered away from the strings, they can only be raised .. but to do that the guitar would need to be modded by adding springs or foam under the pickguards.
The pickups on the one with P90s can not be raised or lowered without modding the guitar
, they deliberately make it difficult by gluing the height adjustment screws in place, plus the pole pieces either side of those screws can not be adjusted without damaging them ( again deliberate) .
The Luke II is similar, to raise the pickups I had to put foam under them.
