I play in a rock band that is fortunate enough to have our own rehearsal space. It's a room in my guitar player's house that is big enough to comfortably fit us all in with our gear, but it gets really loud in there when the drummer starts bashing away. I have been begging them to at least attempt to rehearse at a lower volume, but they insist on playing ridiculously LOUD! The excuse being that you can't lower the volume on drums. The drummer seems willing enough to try a few things, but the guitarist's volume creeps up throughout the session time to the point where I may as well be playing air bass. I have used so called "musicians ear plugs" before, but they're uncomfortable and make it sound like I'm rehearsing at the bottom of a pool. I may just be using the wrong set of plugs. Any recommendations? My ear drums thank you in advance.
