So when are group plays in certain venues specifically the convention center in San Diego the bass isn't as clear as i want it to be or anyone else. I was wondering if someone can help me solve this technical issue. I have 8x10 SWR for the cab and a 750x SWR head. We plug into a mackie and the subs and voice speakers we use are all JBL's. So is there anyway i can fix this in the fixer or what do i have to do in order to hear the mid and the high clear enough in the venue? When i play its mostly just the lows you can hear and if you want to like jam out you can barley hear the mids and highs that i play.
