Shure Beta 91 Kick Drum Mic
Description
The Shure Beta 91 is specifically designed for kick drums and other bass instruments. It combines superior “attack” and “punch” for studio quality sound, even at the extremely high sound pressure levels (SPL) encountered inside a kick drum. Its boundary effect design produces a strong, solid low-end response that has been specifically tailored for heavy bass applications.
