A local band I recently saw did their sound check, and part of it was using a sound level meter for each amplified instrument. I have to admit that their overall sound was very balanced, with no-one drowning out everyone else. Seemed like a good method. 1. Are there any guidelines to this method? 2. Do you use a different target dB level, depending on the venue and crowd? 3. Are the Radio Shack meters good enough, or is there something else (affordable) that will do the job?
