Super-stealthy Boundary Mic!
Want to make that kick drum REALLY thump in your live mix? Wanna cut down on clutter up there onstage? How about BOTH? Here's how: park a Shure Beta 91 condenser boundary mic in front of that bass drum (or in front of any low-frequency-heavy instrument) and be prepared for low-end awesomeness. This thing handles big-time SPLs, lets you choose between a flat response and a punchy low-mid scoop, and even has a built-in preamp - it's a high-performance condenser that's as easy to use as as dynamic. And, the low profile means no more cranky drummers complaining about how the mic stand gets in the way of the band's name printed on the drum head!
