I've searched this and couldn't come up with anything. What does it mean exactly to have frets "dressed" ? I know it has somthing to do with leveling but what exactly is done and how? I have a 10 yr old Yamaha TRB5 that needs a fret job. I figure I need to completely replace the frets but maybe they can be overhauled somehow. I dunno? There are significant indentations on the frets where the string touches the crown. I haven't really noticed anything in playability, buzzing, etc but it looks kinda bad.
