Re: Kentucky Tailpiece Question
If you are referring to the horizontally aligned hooks, these are there because they are on Gibson tailpieces... and the reason they are on those is that they date from the days when the end-windings (loops) were not as reliable as they are on modern strings, and these served to help 'lock' the windings in place, on the secondary hook.
Not absolutely essential to use, but why not?
