Time for a fret job! As with all older guitars, when removing the frets you want to go slow and gently pry out the old frets. Rushing may result in chipping the fretboard. It's always a good idea to heat up the frets with a solder iron, which will melt any glue in the fret slots. Lay the tip of the soldering iron on the fret and coax the wire out of the slot from one side of the fret to the other.
If you do this slowly, you should have no problem pulling out the old frets. I use Fret Nippers to not only pull out the old frets but also cut the fretwire- they work great!
Once you remove all the frets, take a leveling bar or file with sandpaper and plane out the board. This will help remove debris as well as level out any inconsistencies. After the planing out the fingerboard, carefully clean out the fret slots with an exacto-knife or specialty fret slot tool.
To install new frets properly, the fret slots must be free of debris and old glue remains- so take your time cleaning them out right. Once that step is done, installing should be a breeze (hopefully). I like to hammer mine in but pressing them is an alternative. Bend the wire just slightly over the curve of the fretboard radius. Cut them to size, and hammer them in. The frets should be seated firmly, showing no gap underneath. If you can get a slip of paper under the fret- it's NOT seated. Once installed, file down the excess.
After installing all the frets, often a very light leveling, crowning and polish is required. You may also need a new nut to accommodate the change in setup with your new frets. Dress the fret ends and polish them up to a mirror-like shine!
