J 35 in Forum Feedback Posted May 2, 2018 · Report reply I have an old Gibson J 35 ADJ, serial number 052290. It was originally a sunburst finish, but has faded to a dark, mahogany color. It originally had an adjustable bridge which was replaced many years ago with a standard bridge. Needs a little work. I live in Panama and am talking to a shop now. Basically I am just interested in any information available about the guitar.
