I wouldn't run out and buy a Diezel based upon those clips. I hope all who hear this take it with a grain of salt, b/c the Herbert is simply stunning and you don't get that from these clips IMO. Now if you can get folks to play them themselves, that's a differerent story.
It isn't supposed to sell amps - its more fun - and Piero held the BM in his hands for the first time. Normally he's a 7stringer with "normal" frets AFAIK . . .
i just like the second clip, the guy playing the ibanez a bit better. shane is super clean, and it bothers me a bit when peaople judge someones style or the entire sound of an amp on these fun "fly on the wall" type videos. I mean i make my money as a sideman and hired gun for nashville artists and in studio sesions, but if someone judged me by down from up and they said all i can do is modern rock i would feel like that was unfair statement.
just my 2 cents
peace
