Picked one up last week. I've got to say it's by far the best modeling amp ever created. I have a Peavey 5150 and also a EVH 5150 III. The Vypyr has a 6505 model that comes damn near close to the original Peavey head. There's an amazing Marshall Plexi that puts the Line 6 thing to shame.. Other amps included are the Peavey XXX, JSX, Classic, Mesa Rec, Fender Twins, Deluxe and a bunch of others. It's also has a gang of stomp boxes and rack effects. The Tube Screamer sounds just like it.. There have been some reports of people's amp crapping out or not booting up correctly. I guess I got lucky cause mine has been fine so far.. The reps at the Peavey site have stated they will make sure everyone is 100% satisfied no matter what. They are encouraging people to call their customer service if any issues arise. Anyway, it's the best bang for your buck period in a combo amp.. I A/B'd all of my sound samples with the real amps from various websites.. The Vypyr nails every amp!
