Local bars provide. When we play a gig in a huge tent out of town, no point paying for a PA system when we have one. Same when we used to to play more small bars. Same with dances. No house PA. Then what? Don't play it at all? Why is it horrible other than once it is set, it is done. Thus the requirement for solo boosts. We have better monitors than most places we play. I listen out front with wireless. While we do have some times when say my vox aren't quite loud enough nobody cares.
