So I'm in the middle of deciding which Diezel I want to buy. I owned an Einstein quite a few years ago and remember it being a killer amp so that is on the short list as well. My main question is how the VH2 and VH4 really compare. Watching the official VH2 demo with both Peter's they suggested that the ch.2 on the VH2 is a touch more modern with more gain than ch.3 on the VH4? They also mentioned the clean channel being a bit more open and full sounding, both demos sounded great to my ears so I'm not too concerned about that. I should also mention I like to play stuff like Slipknot, Deftones, Meshuggah, Tool etc...I play at home only. I know I should probably consider the Herbert as well. Someone point me in the right direction as I don't think you can make a wrong choice with Diezel amps. Thanks in advance.
