From Our Research Team:

Low-profile Kick Drum Miking Solution!

Shure's outstanding Beta 91A half-cardioid condenser boundary microphone lets you capture a kick drum's true punch, without taking up a lot of real estate onstage. In fact, the Beta 91A excels at picking up all kinds of low-frequency-intensive instruments; its response is tailored for bass frequencies. The Beta 91A's integrated preamp makes it a very convenient condenser, and its ability to handle high SPLs means worry-free use in any environment (even with the loudest live drummers). A 2-position contour switch lets you choose between a flat response or a low-mid-scooped punchy response. You'll love what the Beta 91 does for your live sound!

I love using this mic inside a kick drum. Attack and punch when you needed it by itself or combine with other mics for a paired kick sound.

I'm very happy with my Beta 91! If you're looking for a lot of bottom end with a lot of punch this is the best kick Mic for the job. And AJ, is the best guy to go to for any drum gear questions.

Worked great on harp!

I have used this mic many times on kick drum and it never lets me down.

Recently, I was asked to provide audio services for an outside wedding. A harp was to provide all accompaniment music. I had to make sure that about 150 people outside could hear the harp during the service.
I never did sound for a real harp before. I decided use a beta91a. I attached it to the top of a piece of 1" closed cell foam, and carefully placed that down inside the bottom of the sound board of the harp connected it Into a smallmixer and then to pair of powered speakers on sticks. It worked perfectly, picked up plucks and tone, lows and highs, with no wind noise and hardly any footpedal noise. It was super easy, hardly any eq needed. close [-]
