What is the SM57 best suited to? It’s the most popular choice for a professional musician who wants to mic up their amplified or acoustic instrument such as a guitar amp or bass amp, saxophone, trumpet or drums. It is used on stages and in studios around the world.
How does it sound? The contoured frequency response with its presence rise, helps the instrument cut better through the main mix. The extremely effective cardioid pickup pattern isolates the main sound source and will simply record what you point at it while rejecting sound from the rear.
