Here are two RCA SK-39 dynamic microphones from the 1950’s (2 Available at $150 Each). RCA is known for their popular ribbon microphones but also made some impressive dynamics along the way. These SK-39's are great microphones for effects when looking for a defined vintage coloring. I’d recommend these on almost any source where texture is needed. Both of these have been modded with new XLR connectors. Grab one of these SK-39 Dynamics from RCA!
