It really depends on how prepared you are. If you are rehearsed and don't need a bunch of overdubs, it doesn't take too long at all - (3 or 4 hours maybe for 1 to 3 songs). The range I have seen in this studio is - 3 hours, to over 20 hours per song. You just have to remember that in the studio, time = quality of the final product. If you want a "big" sound, then you need to double some parts, add secondary parts, add vocal harmonies, percussion, loops etc. The point of going into a studio, most of the time, is to eliminate the "garage" sound, which requires isolation during recording, adding certain effects, and using special mixing techniques during mixdown. The actual take of the basic song is by far the quickest part of the process. We don't have a minimum like many studios, so just come on in and we'll try to get the project done within your budget. I really prefer that the band is relaxed and not watching the clock, it makes for a much better time, and better music. Many bands just consider the studio costs of a demo equal to one or two rock gigs, I.E... your first $300-$500 gig will probably pay for the typical demo, two gigs if you spend more time in the studio and want a really good demo.
