There a mic I have had for awhile for live work and I really like what it does. I have known Bob Heil since I did front of house work for him in the early '70's and he's been doing mics for a while now. The PR30 would be a good one to rent or borrow. There are lots of them in LA as they are a hot ticket. It's a large element dynamic. Bob told me he and Joe Walsh hammered this one out. < Bob and Joe are Ham radio pals > These are being used alot. Gibbons has these in his two live iso cabs.
A fabulous mic for a Vox that's pushed is a Beyer M88 and I regret giving mine away, another good mic to rent or borrow.
I don't suggest buying mics unless you know you love what it does. If I was a bit closer than Florida, you could borrow what I have... and see what they do for you.
