I started in the pro audio world during the mid '80s and for the last number of years have been the front of house mixer for http://windbornemusic.com/ working with some of the best orchestras in the world, presenting classic rock music that we all love in a slightly different way.
Within the last year I started personally purchasing and traveling PR35s, 22s, 48s for key positions on the band side and WOW what a difference. Several band guys have commented their ear mixes have never sounded better, and my mix out front is tighter, with much more definition vs volume, which the orchestra's management appreciates.
I don't use Heil's exclusively, but they do get used regularly, particularly the PR30's. When I'm using them, I typically use PR30's for snare, toms, electric guitar, and bass guitar, PR40's for bass drum, bass guitar, and male vocals, PR20's for hand head vocals or snare drum, and the Handi-Mic for harmonica or for mic-ing up headphones for the "lo-fi" effect. I'm so glad Heil has put out this new line of mics. With the fast-paced aggressive music I record, it's great to have a microphone which combines the urgency of a dynamic, with the speed, clarity, and detail of a condenser. The PR30, in particular, has made my year!
