My current band uses an hourly place so we pay $40 for a 2 hour session.
The provided equipment is.......
4 Monitors
2 giant PA speakers
about 3000 watts of Crown power amps
SM57's and 58's
Mackie board
Mesa Dual Rectifier half stack
Marshall JCM900 half stack
Ampeg 810 cab
Ampeg SVT classic head
DW drumset with all hardware
Zildjian cymbals
So we just bring our axes, stick, doublebass pedal.
In the past I have used monthly spaces that have ranged from $400-600 a month
The $600 room was big enough for two full bands, two sofas, a recliner and an entertainment center so with two metal bands the rent broke down to $50 a person. It was also carpeted and had heating/ac. The building its self had no windows and used a key fob system for access. You would swipe the little plastic piece over a sensor on the front door and it would let you in. A computer then logged your entry and cameras followed you all the way to your room. The security was awesome at this place.
I also was at a place that was $300 a month. It had no security, no heat/ac, a concrete floor, no drywall on the inside of the rooms and I once had to chase a rat off of my amp.
You get what you pay for.
