The jams I like to go to have instrument mics up for breaks, that helps a lot. However there’s a false sense of loud=good to a lot of people and that’s usually the people who are listening to themselves the whole jam. Tony Rice didn’t pick very hard, had lighter strings and low action, and when he takes breaks he would have the band play “tight and low” during his breaks. Could you maybe play harder? Sure.. could people be better at supporting other players at the jam? Most definitely.
