Congrats man, glad you're loving it.
I had run through pretty much the entire Diezel lineup and had come to the conclusion that they weren't for me (outside of the Big Max which I love as their take on a JCM800 style single channel amp).
I had never played through a VH4 though. Picked one up just to satisfy that last bit of Diezel curiosity thinking I wouldn't quite jive with it but I was blown away. Pure unadulterated presence, punch and grinding brutality. The character of the distortion is so damn unique, sounds like you're playing in an alien hellscape. Its legendary status is well deserved in my book.
