Here’s a Shure 545SD (Switch + XLR) and 545S (Pistol Grip) Unidyne III Dynamic Microphone from the 1960’s ($135 Each)! 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 more top end than the SM57 and many people prefer them for that reason. If you’ve been looking for a utility dynamic that can cover ground on a variety of different sources, these are the microphones for you! Both of these have been serviced with their old foam cleared out and the 545S has been converted to XLR. Grab one of these classic 545’s from Shure!
