Haha..... Actually studios in SG have their own theme and their own group of customers.
Some cater to the general music kind, so have almost everything, but normally will not allow hardcore or metal in their studios. The equipments also tailor not to suit real heavy stuffs. Needless say, their equipment cost quite a bundle.
Others specially suit to metal or hardcore stuffs, layout is more spartan and easy to maintain. Also easy to single out any broken stuff so as to charge the offending band.
The most spartan kind will have cheap and easily replaceable equipments to cater to the underground or younger customers, who does the most damage. The operators also act as the bouncer, weeding out trouble makers.
Actually if I go crazy and open a "Boutique Styled" studios, I will plough in tons of money to have rooms with names like: Blues room, Metal room, Top40s room, Tone room, Hardcore room, Progressive Rock room, Hard Rocking room, GenX room, GenY room....etc...etc...
All with it's own assortment of specialize equipments and rental rates. Only problem is to have an eagle eye to spot cross-genre bands dispute before it boils over.
