Dear Mr. Guitar,

I've owned my guitar for about a month now and I can't help but notice that the thing sounds awful. Sort of like every note is just a little sharp or flat – sometimes a lot sharp or flat.

I noticed that if I turn those knob-things to which the strings seem to be connected, the string's pitch will change. Unfortunately, when I do this, the knobs end up not facing the same way (toward the front).

Is this normal or do I need a new guitar?

Thanks for the help,
Alan E. ReTentiff
