Here are four Shure 545 Unidyne III Dynamic Microphones from the 1960’s (4 Available at $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, one of these is the microphone for you! All of these have been serviced with their old foam cleared out and come with original 4 pin connectors with new pigtail cables to XLR. Grab one of these classic 545’s from Shure!
