Worked on this LL16M a couple of weeks back.
The guitar came to me badly in need of help. The owner had brought it to a shop situated in our local guitar hub for a bone saddle & nut upgrade but it turned out to be a total nightmare.
Here’s a look at the solid mahogany body. It’s less striking than the rosewood sibling, but I can tell you the mahogany is definitely a great tone wood.
According to the owner, the shop had installed saddle and nut that were off-specs. Saddle was too short (generic 72mm vs Yamaha spec 75mm) and moved in the slot, nut was too narrow (generic 43mm vs Yamaha L Series spec 44mm) screwing up string spacing.
Here you can see that the nut has an allowance of about 1mm on ether side. This threw off all specs and feel of the LL16M neck.
Guitarbear was appalled by the incident. Upon seeing the guitar, I feel very upset that someone would actually do that to nice guitar. If you don’t have the parts or the know-how/skills, please DON’T ruin other people’s guitar.
Removing the blotched job and putting in the correct part.
First step to this rescue operation was to remove this horrendous nut. Plenty of staged photos here, but how else could I show you? 🙂
I used a hairdryer to heat up the glued area so that it’d be easier to remove the “cancerous object”.
I used a small square chip board to gently tap out the nut. Again, this is a staged photo.
Plenty of glue residue. There must have been a huge wad of superglue used. Whoever he/she is, the person who worked on the guitar is a loser. I wouldn’t let this loser come near my guitars even if you pay me.
Next I used 600 grit sandpaper to smooth out the nut slot for installation of new nut. You need to remove the glue residue to ensure a flat surface for the new nut.
The owner had to go all the way to Yamaha service centre to buy a new nut. Although it’s a plastic part, it is far better than one that was off-specs.
See the comparison photo. The differences in string spread and size are obvious.
Fast forward to show how much better the stock Yamaha nut looks and feel.
This is the right way to do things.
Dropping in a bone saddle
Time to shape a new bone saddle. Careful sanding and adjustments are done to get the best height and radius.
Final sanding using 2000 grit to get that smooth finish.
OK, we got a nice bone saddle installed. Owner also brought a set of bone pins for this.
Tip: Yamaha guitars use 75mm saddles, not 72mm.
Again, the same photo to show how important it is to have correct parts (dimensions) if you cannot craft them out from blanks.
Tip: Yamaha plastic nut for L series. 44mm, string spread is about 36-37mm.
Final clean up with Bearclaw Special. Guitar was shiny and happy. Action set up just slightly under 5/64 inch at 12th fret capo on 1.
Super playability and great sounds. Roger is smiling.
