Yeah, I've definitely heard good things about the Mark V.  The thing is, i'm already a pretty big Petrucci fan, i have his pickups in my main guitar (crunchlab/liquifire) and I didn't want to blatantly rip off his tone haha. Not that I could nail it exactly, but I wanted to try and find my own sound a little.  While I do like Engls, I don't have the amp yet so I am open to trying different ones out.  I'll check out a JVM and Mark V, and i'll see about an Uberschall cuz I do like Bogners, I'm just worried about the cleans and the lack of channels.  I don't want to run two different heads.  I have zero interest in Rectifiers and 5150/6505s.  There are a lot of killer amps out there, my price range is preferrably under $2500, obviusly the lower the better but I'm willing to pony up a few extra hundred for the ultimate amp.  It's essential that it has good cleans, a tight crunchy rhythm, and an organic, liquid lead.  Thanks guys.
