I know the only way to know the answer is to do both and compare (which I will next week) but generally speaking: what do you all think? We are in a 10x20 room. We have one (hard rock) guitarist with a combo amp on one side of the room and an extension cab on the other (10ft away). Our drummer is down the middle, as well as my bass amp that sits in front of the kick drum. The amp doesn't have much to do with my sound as I run through a Sansamp DI with blend at 100%, which is my sound. To clear up room I was considering running though the PA with keys and vocals. But at the end of the day, I want to do what gives us as a band the best mix. I am guessing I will have better body as I am running out of two speakers. My tone is simple and in the pocket though, so maybe it is better to stay down the center and not have to much coming out of the PA speakers. What are your thoughts?
