Scott, I don't have one now. Once I bought one from Hank B and tried it for a couple of weeks and traded it back to him. Another time, Gary sent me one to try and I gave it another go. Again, I determined it wasn't for me.
I actually got used to not worrying about the proximity effect because it sounded good. I think it's more of a hassle to plug the extra stuff in and wear the head set and either use a battery pack or run a wire from the mic or transmitter, than to just plug in a traditional mic. Also, I can control the dynamics a little better with a standard mic.
But then, I have turned off most of the automatic vocal settings on the PA3X, such as compression, gate and auto processing, at least for now. I seem to get a better sound using the old method of e.q., but maybe it's just what I'm used to hearing.
I have spent a LOT of time today working on mic settings. Not sure if I'm there, and won't really know until I get on a real job next week.
Try a Crown. You'll either love it or not!
