I have to do vocals at the singer's house in a couple days. I don't do this often (usually at my place or a studio). Any advice on what to do about the room? I have a bunch of 703 that I'm going to bring and basically surround the mic, but leave the area behind the singer untouched. I'm planning on using an AT4040 but will try out a 57. It's a male vocal. Thoughts?
