ACS Live systen on the cheap!
What you have is half way towards a full inear mix with ambient sounds mixed in. Now you have the ambient mix sorted, you'll be hankering to get the rest of it down.

I have a Zoom h4, which might do all of this: stereo mikes for ambient, desk feed into one line channel, bass into the other line input, in 4 channel mode make up a nice mix and iems in the headphone socket. Would this work?
