This is an amazing microphone. With it flat response throughout its frequency range (20Hz - 20KHz) it captures the attack the kick drum very well. Its made to withstand any punishment you throw at it.

I bought this to use with my Cajon. Works great. My Cajon rings a bit but a towel thrown inside took care of it. Thanks Raul for knowing what I needed.

Great mic, I've been looking for a good beater side kick mic for a while. I've tried several options but they were always at least a little intrusive or needed to be heavily gated. The sound of the beta 91a is immediately satisfying; the switch on the underside cuts right where I'd like.

I love the attack that this gives a kick. Mix it with a good sub kick mic, and you have gold!

This half cardioid condenser boundary mic will rock your kick. The beta 91a is specifically engineered for low frequency applications. With a built in mic pre-amp it really helps for low volume settings as well. This mic requires no external mounting and can just sit in a kick drum ready to roll.

I use it in my kick drum when I need to be miked. The great thing is the punch I get from my kick drum. The convenience of not needing a small stand in front of my bass drum is another thing I like about it. It is a little pricey but worth the money.
