As shown in the image, this is an Electro-Voice shock mount 309A. It is compatible with the RE320, RE20, and RE27N/D models from the same company. This is a brand new, unopened item purchased and imported personally from BSW (Broadcast Supply Worldwide) in the US in July 2025. I usually use an RE20 for recording, but I've decided to use a different shock mount, so I'm selling this one. Shipping will be via Yu-Yu Mercari delivery, and I will ship it immediately after payment is received. Please feel free to contact me with any questions or requests.
