I'm selling this because I switched to a Neumann microphone and haven't used this one in a while. I used it with a YAMAHA AG03. I checked its operation before listing it, and it works fine. The sponge has lost its shape a bit. The microphone itself is in good condition as I haven't touched it much. AKG C214 condenser microphone, with shock mount and a convenient carrying case. - Model: C214 - Included: Shock mount, case, manual - Brand: AKG Thank you for looking.
