When Gibson overhauled their very successful Les Paul Standard -guitar about ten years ago, it was decided to offer the model with two different neck profiles.
Most Gibson-fans agree that the best Les Paul necks were the ones on the original Sunbursts, produced from 1958 to 1960:
• In 1959 the neck profile was a well-rounded, but not too big D-shape
• In 1960 the profile was changed to a flatter and thinner shape, resulting in a C-profile
As most things in life, Gibson’s neck profiles aren’t as simple a matter as the company’s terminology will have us believe:
• The ”50’s neck” should really be called a ”1959”-profile, because earlier in the Fifties Gibson-necks were much fatter.
• The ”60’s neck”, on the other hand, is really an ”early 60’s”-profile, as the company moved on to an even flatter – as well as narrower – profile in the latter part of the Sixties.
But still, Gibson’s current 50s/60s-terminology works well with most players when talking about neck shapes.
Gibson’s newest feature on some models is an asymmetrical neck profile, which has a fuller bass side and a thinner treble side.
