I get what this thread is about, and can see why its needed, but something about this isnt clear to me.
When i use my rig as the only source, so no PA support, i have to have it loud enough to get out in to the room etc. Not a problem, i can just turn it up, but how does this work if you have half your stack facing your ears? If i was to put my head in front of my cab id either blow my ears out, or at the very least not hear my guitarist on the other side of the stage.
Maybe the above is an over exaggeration, but the question is, dont you have to turn down once the cab is aimed at your head? If so how does that effect the out front mix if you aren't using a PA for support?
