How to mic our band

Here's something to consider about regarding our live sound: using a single condenser mic for vocals and multiple instruments. The linked article says,

This “old fashioned” technique has made a comeback; for example, many bluegrass and folk bands utilize the one-mic method with surprisingly good result, typically using a large diaphragm cardioid condenser . . .

One obvious advantage of the single-mic technique is that the stage looks cleaner. Gone is the forest of mic stands, booms and cables.

Instead, you have a low-tech, old-fashioned look that fits in well with the music. Setup is much quicker as well: just place the mic, plug it in, adjust position, and you’re done.

So I'm thinking it might be worth getting this vintage-looking condenser mic. I'm guessing we should have two of these shared mics during our performances; three of us can huddle around one mic. I already have one condenser mic and a dynamic mic (less sensitive) that we can use, too. If we figure out a setup, then we can go confidently into any venue and just plug in and play, just making sure that the speakers are placed in front of us, so we don't feed back.
