Thanks. I went to one of the authorized shops here in L.A. and they tell me "4 to 6 weeks just to diagnose". How lame is that...then they told me $75 "expedite" fee. I left, with my amp.
Will try another shop this weekend hopefully. Also, I found this post: http://line6.com/supportarchive/thread/54242
Therewas some good suggestions about testing the connectors in the back (pre-amp out, power-amp in). The thing is, I was direct out when it happened, and I don't think I had any sound.
I love this amp, but this is probably the first time in years I have had anything like this happen. I have used Fender, Mesa Boogie, and Crates in the past without any hiccup at all. To have an amp just die like this without warning really makes me want to advise people against buying them for any professional level uses. It sounds amazing, but I am not even sure it's worth fixing now. I am half inclined to go buy a Vox.
