Truss Rod Adjustments | LsL Instruments

So, you're the proud owner of an LsL guitar and you've decided that the neck needs some adjustment. We recommend that you have a competent luthier do all adjustments on your little darlings. They usually have all the tools and experience needed to do this quickly, easily and accurately. Our advice is to let them do this for you. But please don't let them remove the neck! 

 Here is our procedure for adjusting our necks. All guitars need this sooner or later and it's quite easy but it needs to be done correctly.

First of all, even though the adjuster is located at the neck heel, our necks do NOT need to be removed to adjust the truss rods. Please DO NOT remove LsL necks for any reason except for replacement.

We use an offset, flat-blade, screwdriver to adjust the truss-rod nuts. Those are available at most hardware stores. 

  • Does the truss rod really need adjustment? We set our necks to have .004" of relief at the 8th fret. That means that the neck will have a very slight forward bow (a smile). Place a 12" straightedge on the neck with the strings at pitch. One end should be on the 3rd fret and the other should be on the 16th fret. With the strings at pitch there should be .004" of space between the straightedge and the top of the 9th fret. You can check this with a feeler gauge or a piece of good paper. If there is less or none the truss rod needs to be loosened. If there is more the rod needs to be tightened.
  • Loosen the strings a bit and remove the pickguard screws and then the pickguard
  • Using the offset screwdriver, adjust the truss rod nut clockwise for less bow and counter-clockwise for more.
  • Re-adjust the string action to factory standard of .060" from the High "E" string to the top of the 12th fret. The low "E" we set to .070"  and the rest follow the curve of the fingerboard. Add about .002" of height to each string from the high "E" to the low "E".
  • Play the guitar and check for fret out on the high "E" string at the 12th and 14th frets. With a 7.25" fingerboard radius you should be able to get a full-step bend without fret-out. If there is fret-out then you can straighten the neck just slightly.
  • Go play some music.

If you or your setup person has any questions please don't hesitate to contact us. We're here to help.
