LinearX Instrumentation Microphone M53 NIB

Description

For sale as pictured is one M53 instrumentation microphone made by LinearX (now defunct due to the death of the owner).  This rare item is "new old stock" in its original box; I bought it brand new directly from LinearX with the intention of using it with a new analyzer that LinearX was working on, but unfortunately it never came to fruition before the untimely passing of its designer.  I never used this microphone even once; it just sat on a shelf until now.  Comes with a printed response sheet and calibration data on a 3.5" floppy disk.  Mini-XLR to standard XLR cable is also included.  The pictured mic is the actual one you'll receive.
