I played my acoustic guitar for the first time in a while this weekend and noticed that it was suffering from fret buzz all the way up the neck. I am sure that it was not like that the last time I played it!
A little investigation, with a capo at the first fret and fretting a string at the 14th fret showed no clearance at all at the 6th and 7th frets. Looks like the truss rod needed adjusting to give a little neck relief. I have never attempted to adjust the truss rod on any of my guitars before but there has to be a first time for everything!
I took the adjustment one step at a time; slacking the strings, loosening the truss rod by 1/8 turn, re-tuning and checking. I went through this cycle three times before I was happy. There is still a little buzz on the D string around the 10th fret when playing hard but I am going to let things settle down for a few weeks before I make any more adjustments.
The guitar now plays great again. All in all, a good couple of hours work.
