Dan, I wouldn't worry about that one. There is a world of difference in build quality between the notoriously lousy 70's Gibsons and our own beloved Alembics. Furthermore, the Alembic multi-laminate neck is inherently far more stable than the Gibson one piece Mahogany neck. IMHO, it's like worrying about your Mercedes because your Yugo fell apart after 50K miles.
Bill, tgo
