One of the original OM-28 customs ordered by Eric, which basically started the OM's renaissance. The OM had been virtually ignored since 1934 at which time Martin shortened the scale length. With this Music Emporium run of OMs (18, 28 & 45) being successful enough to convinvce the factory to start them as a new Martin model. The OMs since then have become a sizeable and popular model. This one is 1 3/4" x 2 5/16" string spacing, has scalloped braces and is in virtually new, excellent condition. It's tonal characteristics are big, deep bass and sweet, clear treble.
