Tim,
I have an Engl SE (the midi head), and it is absolutely awesome. I A/B'd it with my friends JCM800 into a Bogner 4x12, and it got VERY close using the crunch channel. The lead channels are ultra heavy and can get a great saturated, singing, sizzling fat lead tone too. Just an overall amazing amp! Just so you know what I'm comparing it too, I have a Diezel Herbert and VH4.
HTH,
Angus
