Not surprising. There's a reason a lot of the top studios in the world have a VH4 in their repertoire. I think the Hagen excels at so much, especially in gig/live environments, it's a players' machine. But the VH4 is versatile - it's super universal in its applications, you can't beat it. The 4 channels are perfect, then the loop is exquisite and the fact it takes stomps up front with ease means you can shape your tone to whatever you want.
VH-4 is the best Diezel... period, no disrespect... and inb4 King Crimson raves about the Herbert... it doesn't get better than the VH-4, and it never will IMO.
