The Vacuum Tube ( AKG C-12 VR)
This AKG Vaccum Tube condenser microphone is much sought after by recording engineers. Its classic tube-like appearance has been retained and some components have been optimized to meet current studio recording demands. It can certainly convert any audio to a clean, perfect sound that many high-end audio companies have been looking for. This model has been improved to have better distortion, low self-noise and is less susceptible to hum interference. The AKG C-12 VR is quite expensive. As of April 2011 its retail price is a whooping $5,499.
