Loud has its place.
Dont get me wrong I have played in bands that are louder than anyone on here. Even today when we do a big show I set up a couple of full stacks for the look.
But I have turned my volume way-way-way down. Why cause people in general do not want their hearing affected by you. OSHA has a formula, anything over 96dbs causes ear fatigue. We actually use a db meter these days, this past weekend we were at 98db. What happens when you take this approach is that you can really hear everything around you, all the little nuances of the music, dynamics become dynamics. You work your gear less hard, your sound people love you, and the audience loves it. Live on stage there are no hot spots, I can walk anywhere on stage and hear all the instruments clear as a bell. When you are younger and I did this up until a couple of years ago, you use volume to compensate for talent, you think if the world hears me loud and proud then Im somebody. Ive learned that isnt so, there is always that person or two who yells turn it up, but believe me the other 200 people there are not in agreement, they are a silent majority.
In my opinion if you are a loud rock band you shouldnt do an open mic. You will have guest musicians, I think you need the smaller combos 20 watt tube amps, not the stacks. I recently went to one to see a friend of mine who plays acoustic. The place had a Marshall Half Stack up there, every guitar player who went up turned it louder and louder to the point you couldnt understand the singers, you couldnt distinguish the other instruments. If I came to your open mic and you are playing too loud, I would just leave, I might mention its too dam loud, but I would leave.
I have never lost a gig because I was too quiet, but I have lost a lot cause I was too loud. Think about that. If you can keep your volume level under control then any venue is possible to play. When I was younger we were limited to the loud rock bars that catered to musicians instead of the general audience out there that could make you some serious money down the road.
But dont listen to me go out there and blast the world for awhile and see where it gets you. If you play long enough you will learn what Im talking about. Another point before I go Tone Has Nothing To Do With Volume, Ive learned to get a good solid guitar tone at any volume level, so why would I beat my ears up.
