First off, when playing live, don't try to get the sound that you normally do while practicing at home... Get a sound that actually can be heard by yourself and the audience... Your low level sound would most likely sound very different at loud volumes, ie as the volume increases, your signal gets more trebly... If you like scooped mids when practicing, chances are you won't be able to cut through the mix live... Normally, I'll bump up the mids alittle and tame the bass...
