These are the first maho necks with a volute Gibson has ever done (on basses, don't know about guitars). Strangely, in the seventies and later, all the volutes were on maple necks which have a higher stability than maho in that area. I never understood why. Even if it breaks all the same, a voluted neck will at least give you more glue surface for a repair so it would have been logical to equip the maho necks and especially the sleek TBird maho necks with volutes.
