Not sure why everyone is so anti LS-10, but I have made some really good sounding recordings with it. I have heard worse sounding stuff/shows recorded with "better" recorders and high-end mics, so I assume after all it's all up to you how your recording sounds. you either can tape or not, you just need some decent mics and a recorder and a bit of knowledge on what to do with the shit and your tape will sound fine. after all, all you do is tape, and audience recordings will never sound like pro-mixed sound desk captures, so fuck it. dont give a shit on what all those haters say about the LS-10, it is just a recorder and has little impact on the final outcome.
I agree on the built-ins though, unfortunately they really suck when it comes to recording a live show.
