Product Description

Celebrating 20 years of John Mayer and his signature Martin OM-28JM, Martin have presented us with another exclusive John Mayer 20th Anniversary acoustic guitar, but this one is glamorously distinct. The Martin Custom OM-45 John Mayer Platinum acoustic guitar is the high-end anniversary exclusive that showcases the very best craftsmanship produced by the Martin Luthiers. For this anniversary model, the border has been enhanced to a fine silver aluminium outline that really makes the grey sunburst pop, adding extra shine to an already stunning guitar. The standout finish really sets this guitar apart from the original with an exquisite grey sunburst that celebrates the 20th anniversary of the OM-28JM. Staying accurate to John’s personal Martin guitar, this model has been constructed using the original specification tonewoods of Engelmann Spruce and Indian Rosewood to supply you with a vibrant, warm, and powerful mid-range giving you that exemplary John Mayer tone. Boasting an Engelmann Spruce top, OM-45 Platinum exerts dynamic ranges of tone by boosting immense clarity giving you the capability to play fingerstyle patterns or vibrant chord progressions.

Martin’s standard taper low-neck profile pins you closer to the fretboard facilitating a variety in playability and comfortability that will enable you to play Mayer’s famous combination of techniques, whether you’re playing fingerstyle or slap and strum. This signature acoustic will give you the ability to experiment and expand the way you play, featuring a unique and limited-edition finish that will be the pride and joy of your guitar collection.

Key Features

  • Platinum John Mayer Anniversary Signature – Designed in collaboration with John Mayer himself, this acoustic guitar features the same specs as his original OM-28JM with an exclusive finish that is unique by design.
  • Low-Neck-Profile – Martin’s standard neck profile provides dynamic functionality to seamlessly move around the neck in a comfortable fashion allowing for a versatile range of different playing styles.
