I'm an active church guitar player and I've been known about these IEMs for a long time but it wasn't until a few months ago I started using them. At first I was impressed how better you can hear the mix and how different it sounds from live audio with no IEMs, I actually like it.
One of the things I've noticed is, of course, there's no external feedback, which means you can't really listen to what's going on with the congregation in matters of are they responding well or not to the music, do I play more, do I stop. So that brings me to my question, will that be fixed if I use couple of ambient mics towards the congregation? Will that give my in-ear mix a close-like live not in-ear feeling?
