Question:

"Vulg4r asks, "I purchased an Acoustic guitar on November 5th 2007. For the first few months, I had no problems. Now lately the 12th fret, every string buzzes, very noticeably. I've tried changing the strings, and adjusting the truss rod. Is there any other advice you can give me before I bring it to my local, overpriced guitar shop?""
