I'm working to record vocals and acoustic guitar, and I'm buying mics. I currently have a Studio Projects B1, and I need to buy a second microphone. I've been told that if I get two mics I shouldn't get two of the same, so I'm looking for some suggestions. Based on what I've learned I'd like another condenser. I'm guessing I'll be using the SP B1 for vocals (but who knows!). I was thinking about a small diaphragm condenser just for variety, but I don't really know where to start. Whatever you guys think is best Here's the kicker, of course. I'd like to spend as little as possible, and definitely no more than $100. I am willing to go used. Thanks guys!
