Picked this up on recommendation from friends, and I'm really enjoying it so far. It's only gone out on a couple of gigs, but so far it's rocked on upright piano and drumkit. Used it on a jazz gig this evening as part of a 2-mic drum setup, with a Beyer M88 on kick and the 450 sat below the ride, pointing towards the snare. It had a really tight sound, great focus on the drums and excellent rejection of other instruments and monitor bleed on the stage.
Brought it as part of my package for larger multi-mic drumkit setups on snare, hihat and ride duty, but loved it on the simple, stripped down configuration. Going to have to get another couple later this year so I can stick it on more stuff at the same time.
