Overall, the Shure 819 is a very good sounding microphone. It isn't the most versatile mic in the world, but if you are looking for a boundary mic then you know what its best applications are and how it might be useful to you and the sound that you are going for. I like using this mic in a variety of situations, but will mostly use it to get a general room sound. It is great for an easy recording of a live session in the studio and I would imagine that this trait would transfer well if you wanted to take it into the field and record a live show. I have also gotten good results with the mic for recording the inside of a kick drum as well as for getting an extra signal for electric guitar. In all of the situations however, I did use the 819 in tandem with another microphone as I'm not sure that I could get the sounds that I was after with only using this mic. I find that when I have two microphone to work with the blend the sound of the 819 with another mic, that I'm much happier than I would be with on the 819. These aren't easy mics to find as they are no longer made, and I've seen there is a big difference in mic's price range. However, if you're looking for a PZM mic that sounds great for what it does, I would definitely recommend checking out the Shure 819 as it is just as good as any in its price range.
