Joe,

The Neumann KMS 105 is an excellent mic and has a wide frequency response curve. Though the SM58 has been the "Gold Standard" for many years, I sincerely believe that technology surpassed the SM58 several years ago and left Shure standing in the wings. Over the past decade, mics have undergone some dramatic changes in overall design, particularly in the types of pick-up patterns and diaphram materials. The Neumann KMS 105 is just one example of these technological advances.

Good luck,

Gary
