A lot of people don't know this but the truss rod (or amount of relief) effects the tone of your acoustic...
I was in a music store today that sold a A101 to a guy and it had some fret buzz... I went in to check it out and noticed that the neck needed some attention. After I finished working on the guitar, I handed it over to the guys in the shop. They were astounded! They couldn't understand why it sounded so much better after an adjustment.
Thing is... A lot of people do not look after the tension on the truss rod. Often the truss rod needs to be released or tightened. (duh, right!!)
Often people believe that the truss rod is there to make it easier to play... (Thats true too), but it also changes the tone of your guitar tremendously.
If your guitar needs a crank on the truss rod, it may sound boomy and dull... If you tighten the truss rod, it will get back the brilliance thats been missing... Also if your neck has too much tension, it will often sound thin, and the action will be quite low.
The reason I'm bringing this up is that people often don't realize this.
BUT ALWAYS HAVE YOUR GUITAR ADJUSTED BY A PROFESSIONAL...
