I recently found that my Les Paul Custom had somehow developed a crack in the back of the headstock. Not a bad one and difficult to pull apart to re-glue it but a bit of a shock to find. Anyone had similar problems with a Gretsch? The Custom is a 1995 so now about 24 years old. This has made me a little cautious about my one piece neck guitars and thinking that scarf neck construction is a better way to go. Any thoughts?
