Get The Tone
Successful harmonies rely on blend. Backing vocalists are aware of this, and adjust their tone, technique and vibrato accordingly. You should too, as a guitarist. Our examples were recorded using a distor ted tone, but ensure an optimum blend by paying attention to the amount of distor tion required, your pickup selection, your dynamic range, the techniques that you are using (so that they complement or mirror the other par ts) and temper your vibrato so that it matches the other par ts.
