It seems like if you tone match a clip, izotope is going to generate an eq for you based on the guitar you are playing, the pickups, and even your picking style and playing, etc. Wouldn't that mean that if you share a tone matched IR chances are it will sound very different if played by someone else? I noticed that when I used your older periphery IR it sounded nothing like what misha sounds like, so I made a tone matched IR to a clip from the beginning of letter experiment for myself that sounded much better. In the end it seems like if you want to get close to 100% accuracy, most people will need to do the tone matching method themselves using izotope.
