Why do people bother with tone clips? I mean it'll give someone the basic idea but it won't sound ANYTHING like what actually being in the room with the amp is like. I have no doubt that the Hagen is a murderous amp. But due to the nature of most recording gear, and especially most people's playback gear... if you'd have told me the clip came from a Peavey that would have been believable as well. 
Anyways... the clip sounded good to me. But without hearing it in an actual mix... I really can't say how good.
