Front End Audio has a fantastic deal on this factory direct B-Stock preamp! This WA-MPX arrived to us directly from Warm Audio quality control where they deemed it as "B-Stock" for whatever reason. We have fully inspected this preamp and you will be hard pressed to find a flaw! However, in the nature of being B-Stock, do expect a minor cosmetic issue but rest assured that it will have absolutely no impact on the functionality or performance of this microphone. Otherwise, this preamp is brand new and carries a full manufacturers warranty. This is your opportunity to grab a deal on a "just like new" WA-MPX from Warm Audio!
