Martin Custom Shop OM-28 just in on trade! Essentially, this is a Standard Series OM-28 with an Adirondack Spruce top (it's also been upgraded with Schaller tuners and Martin's liquidmetal bridge pins, but the important part is that Adirondack top). Overall condition is very clean: it's obviously been well-kept, and sports no significant cosmetic wear. If you've been thinking of acquiring an OM-28 and don't mind buying pre-owned, this guitar's sound offers a beautiful little upgrade without stretching the budget any further. Priced with its original hard case.
