Has anyone ever used the Sony ECM-DS70P for a live concert before ? Do you need a bass roll off, or possibly the Radio Shack Volume Att. ? Anyone know of a great single point mic ? Just interested in everyone's opinion. I used some mic's from sound professional's before to record Interpol & Bright Eyes. They worked awesome, but I want a simple single point mic, I didn't like going thru the whole setup and having wires running everywhere... Thanks for the responses guys !!
