The legendary SM57 is an industry-standard, highly versatile, cardioid, dynamic microphone tuned for the clear reproduction of amplified and acoustic instruments. The SM57 is ideal for sound reinforcement and recording applications. It is the most popular choice for a professional musician looking for a microphone for his/her amplified or acoustic instruments, such as guitar or bass amps, saxophone, trumpet or drums. It is used on stages and in studios around the world. The contoured frequency response with its increasing presence makes the instrument more audible. The extremely effective, cardioid, pickup pattern isolates the main sound source and will easily record where you are pointing while ignoring background noise.
