My acoustic developed a dead fret on the 12th fret of the G string. I looked at it and could see that the strings at the top of the neck were closer to the frets than they were at the lower end. I got it adjusted with the allen wrench that came with the guitar but I wondered why a guitar I bought new 6 months ago would get a bowed neck. Did that mean that the wood of the neck wasn't properly cured? I asked my guitar teacher and he said that on an acoustic guitar there is about 30 pounds of tension for each string, a total of 180 pounds. Electric guitars only have 10 pounds of pull per string.
