USED - Martin OM-JM John Mayer Signature Acoustic guitar

This used  is in 'as new' condition including original Martin hard case. Martin OM-JM John Mayer Signature Acoustic Guitar boasts top-of-the-line construction, with a solid Engelmann spruce top and East Indian rosewood back & sides. Its scalloped bracing pattern & modern belly bridge ensure a beautiful tone and optimal playability. The neck & fingerboard are made from select hardwood with an ebony fingerboard, & the saddle is compensated white Tusq. All combined into a stylish gloss finish.

Sparkle, clarity, and depth. A trio of divine tonal characteristics. And thanks to a rosewood and spruce body, the Martin OMJM John Mayer delivers such beautiful qualities with immense projection. 

Complementing the rosewood back and sides is a gorgeous Engelmann spruce top. Engelmann offers a slightly more mature sound than Sitka spruce, and is the sign of a magnificent, high-end guitar. Not only is it visually stunning, but Spruce also produces a broad dynamic range. This allows for exceptional freedom of sound and begs expressive playing. It is also the ideal tonewood for performing with thanks to its crisp articulation which ensures you can play with an abundance of volume without losing a touch of clarity. Like rosewood, spruce delivers a balanced and versatile tone, so you will never be limited in style. Fingerpick, strum, and slide across the strings knowing every single note will ring out and hang in the air with sublime definition and sustain. After all, these sonic qualities really are what make a premium acoustic guitar.

Endless, flawless fretting

From the body to the neck, the heavenly properties of the OMJM John Mayer are infinite. You can be sure that every part of this guitar is filled with gorgeous tonal attributes waiting for your virtuosic skill to bring them alive. A major feature is the ebony fretboard. It is attached to a select hardwood neck, a welcomed feature for any avid guitarist as such strength is needed for the thinnest part of the guitar. But the ebony fretboard really is what makes this guitar stand out from others out there. Not only does its naturally dark colour contrast perfectly with the bright and glossy finish of the spruce top, but it also brings a wealth of characteristics that make playing the Martin OMJM John Mayer a sublime experience. Ebony's naturally high oil content gives it a smooth and fast finish, lending itself to quick and immaculate fretting techniques. Its high level of durability also means it can handle the frequent attack of your fingertips without wearing away. Whether it’s a simple guitar practice session at home or a sold-out gig with an awe-struck crowd, the ebony fretboard promises to thrive and deliver.

 Ebony also provides some truly exciting sonic capabilities. It is an extremely responsive tonewood that offers a beautifully bright sound, making it a gorgeous accompaniment to rosewood and spruce.  

Incredible stability

In order to deliver an exceptional, clear tone and sustain a comfortable playing experience, it is important to have a sturdy and durable structure. Martin and Mayer have meticulously designed the OMJM John Mayer to provide the utmost stability from the inside. Within the rosewood and spruce body there is scalloped X-bracing which offers robustness and resonance. The scalloped shape of the bracing means parts have been scooped out, allowing the spruce top to vibrate freely and this results in a more dynamic sound that retains structural reliability. Scalloped bracing is an enticing feature, particularly on Martin guitars as it takes us back to their "Golden Era" when all their steel-string guitars featured this sturdy and resonant brace shape. 

The possibilities of Fishman electronics

Project the raw, natural sound of this guitar with bright and full-bodied amplification. Enhancing an already wonderful acoustic is the Fishman Gold Plus Natural I electronic system which pushes every note to the front of the mix without tainting the guitar's authentic tone. Experience glistening high range frequencies as well as a rich low end, every nuance of your playing will be pronounced beautifully.
