This is a Bundled Focusrite ISA One Mic Pre and Avantone CV-12 tube Condenser Microphone. These two together make a great combination for recording vocals, instruments, and just about anything you throw at it. In the bundle you get the Focusrite ISA one preamp which is about and year old. The pre has a ton of gain as well as added extras that make it stand apart from other pres like a built in headphone amp, inserts to incorporate outboard gear, as well as auxiliary inputs for monitoring other sources, and a DI input. Also included in the bundle is an Avantone CV-12 tube condenser microphone which has been owned by one owner for the last 5 years and used moderately. The mic has 9 polar patterns, it's own power supply and nine pin cable ( 48 volts is not needed), wooden microphone case, shock mount, and a flight case that holds everything. Both these items are in great condition with the exception of very minor scratches from wear. Personally, both units, especially the mic, have served me well as workhorse items I've often reached for and relied on to give me a great sound.
