The three bands I play with all leave the heavy gear at my place, I have converted the garage into a studio/rehearsal place, the guys leave their gear here knowing it is climate controlled (Ac in summer, furnace on all times in the winter), Monitored alarm system with motion detection and door striker alarm, recorded wireless video surveillance, reinforced locks and deadbolts, and no worries on anyone using their stuff, when I do have friends over to jam outside the bands, I have 2 bass amps for my own use, a second drum kit I provide for use outside the other bands ( the three drummers all rehearse on the same kit but bring their own hardware and cymbals, second kit is for the non band members to bash on) I have three different guitar amps, a Randall RbX 125, Marshall mode 4 head and cabinet and a bugera classic 55 head and cabinet for the six stringers( I also have 5 six string guitars I have acquired over the years around for backup or if someone shows up just to plink around and make some noise, Thats on top of 7 personal basses and my keyboard and Congas) , I provide my PA system and monitor for use with everyone including SM58 mics (if they want other mics, they bring their own).
I own the recording gear and a full compliment of SM57 mics for the cabinets and have a 16 track recording console (along with the vox effect processors Xovers, compressors and EQ's and 5 sets of audiotechnica noise cancelling headphones and headphone amp for monitoring while recording), all available for use with a heads up to set up for it , free of charge, no one pays a single cent of the costs involved , because , after all I set this up SO people can enjoy it , the costs of power and gas for heat is relatively cheap.
I also carry 100 grand contents and 2 mill liability on the space too so if in the unlikely event that someone does get in and rips us off , we are covered. All I ever ask is a few times a year they show up to clean the room up and keep things reasonable in order and maybe a little sweat equity when we have improvements to make ( IE: this spring we are doing up a new recording booth and a vocal booth to record with) everyone seems to be happy with the arrangement , but the place does get messy , because it is mainly a boys club after all and no one bitches about beer cans and such.
Some people think I am nuts to do this , but I Have always wanted a spot like this and can finally afford to do it , and I have a secondary agenda as well , The recording studio is going to supplement my investments and retirement savings when i retire, I already rent out for recording and engineering , so its not all a free ride, but the bands i play with have priority to the point there is a person or band that needs a demo done or tracks recorded, I don't usually master , but I have been talked into it on occasion
But, if you don't leave any gear, you won't need to deal with it.
