Setup Information

Nut Action

The nut is the piece of plastic, bone, metal or other synthetic material which spaces the strings out at the top of the neck near the tuners. Nut action indicates the depth of the slots in this material and therefore the height of the strings above the 1st fret. The lower this number is the closer the strings are to the frets. A general guide for good action at the nut would be:

E: 20 | A: 18 | D: 16 | G: 14 | B: 12 | E: 10

but I may make this higher or lower based on the player and other considerations for the guitar.

Relief

This indicates how straight the guitar's neck is.

0 : indicates a flat neck; this is good for even action all the way along the neck but may introduce buzzing if the strings are strummed particularly hard.

-n : any number which is negative indicates the neck is "back-bowed" pulling back against the strings this should be corrected as it will cause buzzing in the middle of the neck.

+n : any positive number shows that there is a dip in the middle of the neck caused by the strings pulling against the neck this is usually a good thing if the number stays low as it allows the strings to vibrate without hitting the frets in the middle of the neck.

Generally around +5 is a good amount of relief but lower numbers right down to zero can be used to give very low action (good for very fast players).

12th Fret Action

This indicates the height of the strings above the 12th fret and gives an idea of the feel of the upper register of the fretboard; as with the nut action the lower the number the closer the strings are to the frets. This measurement is in millimetres as the tool I have for measuring action here is in millimetres.

Electric guitars usually are best with around 1.5mm across all strings although for those who drop tune I may raise the bass strings to around 2mm.

Acoustic guitars may have a range a little higher than electrics to accomodate heavier strumming:

E: 2.5 | A: 2.25 | D: 2.25 | G: 2.0 | B:1.75 | E: 1.75 would be a good number.

Other Information

Here I'll indicate all other information I think is pertinent and also give a breakdown of all the work that has been carried out during the setup. I may also note down things which haven't been done as they aren't necessary but could be carried out in the future if the customer wanted it.





Initial Other Information

The relief on this guitar is huge nearly 3x higher than I would recommend. This could account for some of the overly high action on the nut, although this is still quite uneven. Action at the 12th fret is not too bad, odd since the rest is so far out. Several frets have been leveled but not re-crowned (the rounding of the top of the fretwire). Further inspection shows leveling was not completed properly for the 14th fret and several spots of other frets. String gauge is currently 11

Current Other Information

Adjusted truss rod. Adjusted nut string slots. Re-shaped nut. Re-crowned fret tops. Smoothed fret ends. Removed shim from saddle slot (unnecessary after doing the setup). Installed 10 gauge strings and cleaned guitar. Final check
