This sweet 27 year old Sadowsky J-bass has been through the shop before and this time in for some high / loose frets. Before leveling the frets, I glued and clamped down all of the frets to ensure they did not move. On rosewood fingerboards my glue of choice is thin superglue. This was a finished maple fingerboard so superglue can make a mess quickly. I opted for slightly thinned down yellow glue to penetrate down into the slot and easily clean up. Now the frets are ready to be leveled, crowned and polished. This player prefers electric guitar action (ie low) so precise fretwork is critical.
