Here is an old beauty that came in for some guitar repairs. A 1970 Gibson J-20 acoustic guitar, which my customer bought new. Wow! It is in real good shape for a 39 year old guitar, except for wear on the fretboard from lots of use. The guitar repairs are actually fairly simple and straight forward. The neck has a tiny, barely noticeable hairline fracture at the area where the neck and head come together. Therefore allowing for way to much forward bow and very high action. Our goal is to fix the neck, make a hand carved bone nut for the bridge and neck, and level and polish the frets.

Old guitars usually need these type of repairs, although, as I have said many times, all guitars need bone/s nut and good setup, even new ones.

To fix the crack, since it is a hairline fracture, I will:
#1. Pull out the first and second frets. I use a special tool for removing frets without damaging them. I also use the correct procedure when using the tool as to not damage the fretboard.

#2. Drill 4 1/16 inch holes. One on each side if the fret right over the area where the fretboard is glued to the neck on each side of the fret.
.
#3. Put a drop of TiteBond glue in each hole. i use a mini dropper, which is like a tiny basting tool to get a drop in the hole and not on the fretboard or guitar neck.

#4. Install 1/16 inch wood dowels in each drilled glue hole and clamp the area with the proper clamps and let it sit for two days.

#5. Carefully reinstall the frets, level and polish the frets and carry on with the setup, then hand carve a bone nut for the bridge and neck.

Realistically speaking this is not a difficult job. It does require precision and experience to pull it off. The bottom line is to make an effective repair at an affordable price. We know it is a success when our customer picks his guitar up and can’t even tell me where the crack was, and more important, he will be floored that this is the best his guitar ever played in the 39 years he has owned it.

  7. wow, nice oldie. I hope your client is thrilled.

  8. I have exactly the same model 1970 Gibson J-20 guitar shown on your web site. However, the guitar you show appears to have replacement tuning pegs as the originals would not have been chrome. How much would you value the J-20 for?
