I was recently at an event that featured Peter Denenberg (produced the Spin Doctors) talking about recording techniques. One of his favorite tricks is to put two SM57s on a guitar amp--one on-axis, one off axis, both mixed to the center. Immediately I thought, hey I can do that with my X3 Live. This is an easy way to give your amp models a fuller sound. Just duplicate the settings, except have one mic on-axis, one mic off-axis.
