L-5 Help! in Gibson USA Posted July 16 · Report reply Hey all! A guy I know is selling this L=5. He has no specific info about the guitar other than "it is old". I like the guitar and want to make him an offer but I have my doubts as to it's authenticity. I've never seenan L-5 with the toggle on the upper, bass side of the guitar. every single one pictured on the internet has the toggle on the lower, treble side. anyone have any input?
