I'll be playing at an outdoor gig next month and would like some advice as to which combination of speakers to use. For indoor gigs, I like the sound of my Aggie GS 112 and Bergantino EX 112. I also have a 4 ohm Avatar SB 112 which I've never gigged with. I can't play outside around my house to try them out so have to ask for your help. I have the Eden WT 550 amp.
