In Buddy’s words: The wrap-around neck on the original guitars was replaced with the bolt-on design some time in the mid sixties. That change was short lived because the bridge was bolted to the neck, which defeated the purpose of the independent wrap-around design [a neck that mounted independent of the bridge and keyhead to avoid the tuning problems associated with temperature change ]. By the end of 1967, Ron [Lashley] went back to the wrap-around neck with a cutout in the tail end. This cut-tail design has remained the standard for all Emmons guitars.
