Okay, I am an electric guitar player. I own a Fender brand Squier Strat. Here's the problem I'm having. The tuning on my guitar is fine, it's not the pitch of the notes that is giving me the problem. You see, when I play the first through fourth frets on the guitar, especially on the A string 4th fret, it tends to buzz a lot. However, any frets 5 through 21 (the highest fret on my guitar), it sounds pretty good, with very minimal to no buzzing. Does anybody have any idea how to fix this?
