Left Hand Tone Tip #2, Position

Another factor that can compromise the tone of your fretted note is improper position in the fret space. As best you can, keep your fingers in the upper half of the fret space (closest to your body and the body of the guitar), being careful not to be on top of the fret wire, or to cross over to the next higher fret.

Experiment with fixing the tone of your funky note by adjusting your finger position in the fret space. If you figure out what the problem was, be sure to make a note of it, and let your hand memorize how you went about fixing it.
