virtuoso u say....
marshall would be a good pick. why?
even if u turned down the mids, there are still f***ing mids!!
u need the mids to cut thru the recording instead of raising the volume..u would get drowned in the lower freq, so stay in the mids!
less than a thousand....i've played the JTM45 tube amp and kicks ass esp when u have the effects to drive the clean channel(the only channel)..if not, u might want to listen to the DSL series, shouldn't fare too badly either..
hope it helps!
