Thanks, John. So, the main difference is the directivity, or I guess, the spectrum in front of the mic that the mic picks up sound from? With the 104 picking up sound from a wider spectrum?

The reason I ask is I am able to get a very good deal from a friend that is selling a barely used 105. My daughter, although only 15, has been performing live (and some in the studio) for about 2 years now, so I do not think mic technique will be a huge issue...

Anyway....thanks again. I really appreciate the help.
