Here's Shure 545 and SM57 Unidyne III Dynamic Microphone from the 1960's and 70's (545 - $135, SM57 - $175)! These dynamic microphones were the precursor to today’s SM57 and were built in the USA with the highest quality parts available. The 545 has generally more top end than an SM57, and vintage SM57's sound less sterile than modern 57's. If you’ve been looking for a utility dynamic that can cover ground on a variety of different sources, one of these microphones are for you! Both of these have been serviced with their old foam cleared out. The 545 is in mint condition with an original 4 pin to XLR cable, and the SM57 has wear to its body. Grab one of these classic dynamic microphones from Shure!
