I just got a hearing aid. I find it helpful, I have a fair bit of loss above 2K. I tried it at a rehearsal tonight, it seemed fine and i'm thinking of using it at a gig Saturday night. I play in a rock band, but not a loud one. I use a 15 watt amp and we play fairly small clubs usually. I'm just a little concerned that it may amplify it too much and damage my ears. I use it turned down quite a bit, and turned it down at bit more at rehearsal. Does anyone else use one while playing with a band?
