Adding even more presence to the legendary SM-58, the Shure Beta58A dynamic vocal microphone is precision-engineered for professional live sound reinforcement and studio recording applications. A tailored frequency response accentuates clarity of vocals and a tight supercardioid pattern insures high gain-before-feedback, maximum isolation from other sound sources and minimum off-axis tone coloration. These rugged stage microphones last and last and are great for touring musicians who want that little extra something in their vocal sound reinforcement.
