VH4 is a great amp. It's flexible in that it can be dialed in to sit well in almost any genre of music, but IMHO it has an inherent VH4 tone and structure at all times. If the sound in your head strays outside of the amp's comfort zone, it can start sounding very average (at best). For example, I don't think the amp particularly likes having that real saturated, dripping wet with gain type sound. It can do it with the gain turned up, but the amp gives me the impression that it's not happy about it. That's fine with me, because I like the gain to be right at the cusp of saturation, which is where the VH4 excels IMHO. So as all amps, best to try before you buy.
