To commemorate the 20th anniversary of John Mayer’s popular OM-28JM model, Martin collaborated again with John Mayer to offer this gorgeous high-end anniversary model. On John’s first signature model with Martin, he chose to include an aluminum border around the headplate and bridge. For this anniversary model, the border is expanded to the fingerboard and pickguard, and the border has been upgraded to a fine silver that will look amazing for the life of the guitar. Like Mayer’s previous models, it includes a thinner 1 11/16th width at the nut for comfort and speed. It also includes stunning satin nickel Waverly tuners. This edition includes a unique label with Mayer’s signature, and it is limited to the calendar year 2023, so make sure to check it out soon!
