I'm looking for a good amp for less the $1000.
I'm playing out of a Randall RG200GH, or something.

I'm looking for a pretty versatile amp.. I play and perform all kinds of music... jazz and jazz fusion, blues, hard rock, metal and shred.

I'm looking at the master tube series from carvin now, and they seem pretty good, but are there any other good amps for my price range?
Try looking up the Line 6 Valve HD100 100W Head. It's an $800 tube head with many built in effects. I'm only looking at this online, so haven't had any true experience with it, but all the reviews I have read are praising this amp.
