When Guthrie first started using his Fractal Audio FM9 setup for live performance, he said that he still planned to use real tube amps in the studio for recording. I found that interesting.
I like and use both modeling and real tube amps. But, I tend to think of tube amps as being more appropriate for a live playing situation. I find modeling very convenient for recording. But, obviously, there's no reason either paradigm cannot be used for recording and live performance.
The first demonstration recordings I heard of Guthrie's early FM9 live setup sounded lousy to me. Yet, I think it was, probably, hastily recorded with cam microphones. I assume it sounded better to the audience at the, actual, live performance.
I noticed that Govan has added a real amp behind him, on the stage, for the feel. He's using modeling for the added versatility of sounds, things tube amps cannot do. It gives him a much wider palate of sound textures with which to work. Modeling gear is also lighter, hauling it around from gig to gig vs hauling multiple real amps.
I found his thoughts about wood in the video and his simple demo of wood resonance amusing. I've always assumed that wood made a difference in the sound ever since I swapped Strat necks and discovered that even different necks, different fingerboard woods, sound different. And, who has not played, at least, one guitar with a dead spot in the body? I certainly have experienced dead wood planks.
