The wolfgangs actually have much
thicker necks than most guitars. *The difference lies in the string spacing and, to a lesser extent, the radius. *The wolfgang necks are about .1" thicker than the standard
Ibanez neck...
If you compare the string spacing (especially the distance from Low E to High E) you'll see that the wolfgang neck is MUCH smaller in this regard. *What the add in thickness they take away in width.
There is no way you can make your Ibanez-style neck like a wolfgang. *You'd have to do so much cutting and rebuilding that you could buy 3 wolfgangs by the time you were done.
