Report Any 60's Everly Bros experts around? in Gibson Acoustic Posted April 5, 2017 I believe they had scalloped bracing in some guitars out of the 40s and 50s, but by the 60s it was not a standard practice at Gibson. So why not just get a righty and have a skilled luthier make a lefty bridge for it? I'm guessing it would be pretty straight forward if they had the original. As long as you kept the original, don't think it would have much impact on resale if that was a concern (as long as it's with hide glue).
