Yes dividing and planning the parts is essential. But as far as EQing is concerned, I ask myself: is it better that each player EQes its own instrument at the source (like the amp, for example) in order to have the "final" sound coming out of the PA, kepping the desk EQ flat, OR is it better to just set up each instrument sound the way the musician likes it the most, and then correct the final mix with desk EQ knobs? So long story short: is it better to EQ "at the source" or at the final stage?
I mainly played as a classical guitarist for the last 10 years or so, hence I never had such "problems" to face in the classical guitar world! :lol:
