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

Guitar seems to be in pretty good order. A little scuffed and worn, also strings are very corroded and tuners are showing corrosion as well. Frets are showing a little wear mostly on the B and high E strings. 12 gauge strings currently

Current Other Information

Adjusted truss rod. Lowered high E B and G string nut slots shimmed whole nut to raise low E, A and D strings for more even spread. Levelled saddle slot bottom which will improve vibration transfer to the guitar top see pics. Reduced height of saddle. Re-shaped nut for reduced dampening (see pics). Cleaned guitar and fretboard. Oiled fretboard. Tightened loose tuners. Fitted 13 gauge strings, readjusted truss rod to compensate for higher tension strings. Final check
