So I share a rehearsal space with some guys in one of my bands and I leave a rig there (Markbass LM III and MB 4x10). When I have gigs that don't have a back line I'll use this rig but most of the time it lives at the space. I pay $100/month. One of the guys in the band I play with at this space is in three other bands that also use this space and he uses my gear. So far there have been no issues, the gear is always left clean. And I don't think anyone is cranking this rig or playing at peak levels. But I feel like I'm being taken advantage of since none of the other bassists using my rig have to bring anything, I also have a bass there that is probably being used, I'm getting no money from this deal, and the wear and tear on my gear is increasing because of people I don't even know. Can a cab or head get worn or damaged just from normal use? I know tubes need to be replaced occasionally but the tube in this unit is a gimmick more than anything else. Curious to hear other people's thoughts.
