Shure KSM353

This Microphone is New Old Stock. Meaning we ordered it brand new from Shure, lost it in our back stock for a few years, and have now located it and placed it into stock. Hence it's low serial number. It has never left our building since arriving from Shure. It's never been sold. It has only been pulled out of it's wooden box to take the pictures for this listing. It being NOS is also why it has the older Shure wooden box, vs the new aluminum case. It does not have the original cardboard shipping box from Shure. The Shure shock mount and paperwork are still in the sealed factory plastic. The price is the current asking price from Shure for this microphone. It's a great way to get an untouched older version of the mic that comes with the no longer made fitted wooden box. The bottom of the box has 3-4 small scratches on it from being moved around in our back stock cabinet.
