How to mix an acoustic duo
Well I wrote some advices and read only afterwards that you're asking about live mixing. :rolleyes: But mostly the same principles work either way:
I guess you've panned everything appropriately? Guitars on the sides and vocals in the center or a bit sides if it's more like a duo singing.
If the guitars aren't good together, carve let's say some low middle out from the other guitar and add some to the other and maybe some nice higher middle vice versa. So that they sound at least a bit different. If it isn't working in any way and they are fighting each other maybe it's because of the arrangement of what they play, think that also.
You could try some sidechain compression so that the vocals duck some middle of the guitars. (Harder to do live depending on your gear)
Try to listen what frequencies are the most prominent when everything is playing together. If it's the muddy low middle take some out from guitars or vox, whichever sounds most natural.
Make all the EQ fixes while everything is playing together so you'll hear how it affects the mix, not only the instrument you're working on. (Well, It's ok to do some really fine surgical EQ as a solo.)
Use low pass filters if needed. No use to cut the lows too high if it isn't boomy and sounding bad. You can even boost some nice sounding lows on the guitars.
I'd compress the guitars and vox a little to quite a lot depending your taste and how good the players/singers are.
You're practicing in a garage so I'd say the room emphasizes the muddy and boomy low middles. Try to find the worst frequencies and cut.
Mostly some random advices but they work in most situations. Cut the bad narrowly and boost the good widely :ph34r:
Sounds like it's the low end giving you trouble?
You can send me the files and i'll gladly give you a quick mix.
