I have a Kramer Duke that I can work on now that I have another bass. The fretboard is coming up a little bit at the 24th fret. I think I'd have to remove the entire board and get off all the glue and then reglue it. The fretboard is ebonal. I have read that an iron should work. Would an oven heated to 150 with me covering the bottome rack with pans to block any direct heat work well? I just figure that is probably less heat directly than an iron... Also any chance they used a glue that won't soften with heat?
