I built all our speaker cabs so I defo own them. I also bought the amps, rack gear, mixer, cables, lights and smoke machine. Drummer owns drum mics and his vocal mic, singer owns his mic and guitarist brings vocal mic and amp cab mic. I dont charge the band for it as they're all really grateful and all help lifting it in/out of venues and all put cash in if something gets danaged and needs replacing. Main thing is they all say thanks.
It does however give me leverage. We had a drummer who started complaining we weren't getting enough cash. I do most of the booking leg work so when he started stropping with me the rest stood firmly behind me and eventually he got turfed out.
I'd like to think its cos I'm popular but I'm realistic enough to know the truth.
