Just wondering what techniques some of you may have for double tracking riffs where the guitarist may use a lot of vibrato, artificial harmonics, or even bends. Obviously the most ideal would be to have the guitarist play those dynamics exactly the same both times, or close enough so they aren't dissonant, but this can be difficult and time consuming even for the greatest players. Is the best bet to get them as close as you can and then edit with a little pitch correction where necessary? Interested to see what people think on this. Thanks.
