It's been 2 years since the last time I played guitar. I tried to play again this morning and something feels off. I felt sore on my wrist when trying to play barre chords for just a few strums. I don't know if it's just my hands not getting used to after 2 years of break.

I remember something about action and measured my guitar's action. And there is quite a gap between the action on its 1st fret and 15th fret. The action on the 1st fret is around 1 - 2 mm and 5-6 mm on the 15th fret. I'm not sure if this is normal or not. For comparison, the action on my electric guitar is pretty much the same across all fret (1-2 mm on the 1st fret and 2-3 mm on the last fret).

Should I adjust the truss rod? I never do this before so I'm worried if I broke my guitar because of it. Here are some pictures of my guitar's action for reference:

15th Fret: 15th Fret Action

Look down the neck and see how its shape is compared to the very straight strings. It probably needs a tweak of the truss rod, to bring fingerboard and neck more closely in line with each other. Compare with the other guitar and you'll get a better idea.

    I agree with Tim's advice, but would simply recommend using small truss rod adjustments, like an eighth of a turn or so. And don't force it! If the adjuster becomes stiff, you may be a the end of the threads; continuing to force it may break it at that point. Lastly, allow some time for the guitar to settle before making another adjustment; I prefer overnight.

  • @Tim I looked at my friend's guitar. Its action is more or less the same (we both took a break at the same time and have the same model). I tried to look down the neck from the headstock and from the bridge but can't find any curve.

  • @KirkA I did a half of a turn after looking at my owner's manual. Alas, no change on the action height. Maybe I should bring it to the shop. It bothers me how tight it feels when turning the truss road. I thought I was going to break my guitar.

  • Bringing it to the shop is the right thing to do in my opinion. Ask the luthier to teach you some stuff while you are there.

  • Is it possible that the action is supposed to be in this height for my guitar's model? Considering my friend's guitar is also in this state. I couldn't really remember how high it was when I first bought it.
