Shure SM58 Microphone with PGX2 Transmitter
This legendary Shure vocal mic is tuned to accentuate the warmth and clarity of lead and back-up vocals. Consistently the first choice of performers around the globe, the Shure SM58 is a unidirectional (cardioid) dynamic vocal microphone designed for professional vocal use in live performance, sound reinforcement, and studio recording. A highly effective, built-in, spherical filter minimizes wind and breath "pop" noise. A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The SM58 has a tailored vocal response for a sound which is a world standard. Rugged construction, a proven shock mount system, and a steel mesh grille ensure that even with rough handling, the SM58 will perform consistently. Outdoors or indoors, singing, speech - the SM58 is the overwhelming choice of professionals.
