I been wondering about something I've observed, and was talking to a few other players about; and that's amps seeming to have less clean headroom as a night goes on, and rumors and speculations that it could be partly due to the amp's build up of heat?
Now its also reasonable that other factors are there in play that would blend in to this;
- 'we tend to get louder later' - This could be huge. Not only would we be running amps harder but there's also that thing that as the sound levels go up, so does the sound density, less space' to perceive what we'd hear as room for 'clarity.
But, being aware of that and a decent amount of experience, and taking it all into account, seems like it's more than just that.
- our ears change
- line voltage sag. I'm pretty sure I've seen this- at one venue ('venue' a frikin auto garage shop - the amp folding' rather hard on band peaks, and at least one other player looking around at his amp going 'WTF? But I didn't get to actually see it on a meter.
