Yesterday, I did some research on how to create EQ matched IRs.

I recorded a (mono) track with my favorite patch on the 11R. I then plugged into the AA3, and turned off the cab modeling. Recorded the same riff, using just the amp. Did some EQ Tone matching, and created an IR.

I then used that IR on the patch that I recorded in the AA3, and the tone was dead on!!! In fact, the patch had more clarity than the 11R patch. I went back and tried several other patches, that I've used for years, and for some reason, they sounded a little muddy to me. Maybe the clarity of the AA is better, or maybe it was just dumb luck.

This may be a turning point for me. If I can replicate the sounds from guitar tracks from songs using this method, I may actually move on from the 11R.
