03 Visiting Studios Make sure that the sound engineer is experienced in making your style of music and that the studio has the tools you think you'll need.
Ask to hear some of their previous work if you're unsure and if you're not familiar with the equipment side of tings, take someone along who is.
Make sure that the price quoted includes an engineer - unless you've got your own that is.
Don't hand over any wong until you're sure you're actually going to record and when you do, read any small print there may be very carefully.
Chances are you're going to be walking with your demo for a while so if there isn't a decent studio in your area it's worth travelling until you find one that can, rather than just using one because it's close by.
