This Martin OM 18 Authentic 1933 is light , real, and incredible.  It is in EXCELLENT SHAPE!   The tone is balanced full, and jumps out of the guitar.  It is loud if you want but is capable of whispering as well while providing full balanced rich tone at any volume.  The action s just like when it was born!  These were built from 2013 to 1019 and only 412 were made.  You don't see these around and it is because owners love them so much!  As with all Authentics, this guitar was produced on the Custom Shop at Martin with a hand carved neck and hide glue throughout!  It has a beautiful set of Mahogany for the back and sides as well as a nice Adirondack Spruce top with the VTS (Vintage Tone System).  This is a beautiful instrument and a total joy to play and listen to.
 
It has a slight bit of perfling/binding lacquer cracking on the top near the neck joint but otherwise is in Excellent shape.  The finish on this Authentics is very thin just like the originals and this can happen.  It is very easy to touch up if you would like but it doesn't affect playability or tone.    The Smokey Sunburst top is so period and organic looking.  It's so rich man It just gets my blood flowing!  These guitars are my favorite Authentic because of the awesome tone, sustain, and volume.  Grab this one quick!
Thanks for stopping by!
