Re: Ibanez Necks
Being a Prestige neck does not have anything to do with the thickness or width of the neck, it just indicates the neck was treated and finished in a specific way to give it a more 'played-in' feel.
That said, a Prestige Wizard is nothing more than a Wizard that was given a specific treatment. And the Wizard differs from the Wizard II by a few millimetres, I think they're 19 mm at the nut and 22 at the 12th fret, from memory. I may be wrong though.
