Hi! Is there anyone out there who owns a SJ Deluxe acoustic? I bought one new in 1974 and still have it. It has a great tone and a beautiful multi-point pickguard similar to a new Sheryl Crowe model. It has a top crack from the end of the fretboard to the sound hole on the treble side. Does anyone have any suggestions about a fix? I'm looking forward to hearing from you.
