Just remember to leave it on stand-by as soon as you get there to let the valves warm up properly. Cant beat the sound of a nice warm valve! When im using my sound city at gigs i often get the early, set my rig up andc just leave it on stand by while i have a few drinks and wait for the band to arrive, by the time i hit the first note its usually been on for an hour (probbaly overkill but sounds immense!)
