Also, I don't belive for one minute the guys saying that they would prefer playing without a P.A., at ground level, to 20 people over doing the "big gigs"
Very true, but IME a club has either no PA at all, a PA for vocals only, or a sweet ass PA that's meant to amplify every instrument in the band. I'm always super stoked to play the latter & even then will be mic'd. It's the two former situations where I'm glad to have headroom and a big rig apart from the fact that I love the tone.
