My buddy is thinking about one of these... (Gibson Custom Shop 1960 Les Paul VOS Plain Top) -Are these guitars from Guitar Center inferior in any way to a regular historic or vos? -Do they have a long neck tenon? -Maybe it's cheaper because it has a plain top? -Are they chambered? The 1960 VOS seems to go for a lot more money. This guitar is around 2900 new at GC.
