Re: Thoughts about amplifiers at 3/4 volume.
Maybe I don't drive full out all the time, but I have plenty of shows where if I don't need the full output of the box, it is easier to turn back the gain a bit and keep the rest of my gain structure through the system the same, especially if I am also doing IEM monitors from FOH. I seem to have often heard that gain is gain. Take it away from the place that affects the least other things.
That doesn't mean I also haven't done plenty of shows with the master fader at half mast.
Spending most of my time in the bluegrass/acoustic world, I can't think of a single time in years I had a problem with anything in a system clipping frequently. In 4 years of ownership and a couple hundred shows, I have never seen the clip lights on my QSC's. I guess I am not the guy out in a high performance car, I am the guy out for a slow sunday drive with cruise control.
