Great product! Great value!


I use this mic for my slap top cajon and it works great! Fits perfectly and sounds incredible! Thank you Sam Ash!



Perfect for my Cajon


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, sounds and functions just like I want.


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. It's hard, slapping, and thudding without sounding round, woolly, or boomy. The mic is super durable and heavy. I still had to gaff it down to stop it from moving but on lighter drummer it probably would be fine. Again I really love this mic, it'll likely be my first go-to kick mic moving forward.



Sick mic.


Great staff and great deal. Using this for kick drum and cajon gigs.



Killer mic

My favorite kick mic


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




A great low frequency mic!


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. Also works well in some piano applications.

Great for Kick Drum


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.
