I realize this is subjective, but I'm looking for feedback on what others are hearing and feeling based on their volume settings. I run my Kemper directly to the FOH and use a powered monitor next to me to hear. I know that most of the info says the amp volume should be at 12:00 or at least start there, but I am getting a lot more feeling and response as well as the "amp in the room" feel (people talk about by adjusting the cabinet volume) by simply setting the amp volume at 3.0 (not 3' oclock) ~2:00 or close to it. Some amp profiles are really dark at 12:00 (with eq's as profiled), but when turned up slightly they really open up and I can get the feel and response at any volume the monitor speaker may be set at. I am typically setting the master volume at 4.0 - 5.0 and that allows the sound guys to turn FOH levels up or down, but the response and harmonics are really on and more noticeable. So are there any rules of thumb people have developed while messing with volume settings?
