For the record, it wasn't direct into the P.A, as I said, he was using a Peavey Triple XXX cab, and it was definitely mic'd up. I didn't see the Macbook myself, but I guess it's plausable...
And ease off on Bloodroot some, guys, please. He has his own way of getting stuff across that can seem harsh and abrupt, but everyone has an opinion, and they express is it their own way. His just isn't very subtle
My personal experience with Line 6 stuff isn't so bad. I definitely prefer tubes, as I'm sure the majority of you guys do too, but when it comes to what the modelling stuff does, it's starting to get much better. I've only been using tubes for the last year and a half, and before that was using floorpedals to get high-gain tone. My Toneworks AX1500G always sounded much better than the Randall an old bandmate had (we fell out cos 'him + guitar = garbage'). Look at Roland cubes, for instence, they sound really good, and much better than Line 6, IMHO, and work on the same principles.
The way I look at it is that modelling stuff can be AMAZING for clean work, much better than I've ever coaxed out of a 'real' amp, but the distortion and general high-gain stuff isn't quite up to scratch yet, but that's gonna change very soon, I'm sure.
