OM-45 John Mayer 20th Anniversary Guitar

These guitars have been designed to satisfy the needs of a small, select group of the worlds most respected and most popular musicians. The John Mayer and Eric Clapton models are highest quality instruments for the demanding musician, true fans and collectors.
Johnny Cash fans have a choice of either a black D-35, just like the one he used to play, or the posthumous DX Johnny Cash for the fan on a limited budget.
Finally Martin regularly releases their CEO models in accordance with C. F. Martin IV or more recently the new CEO Thomas Ripsam. These are limited runs, using unusual woods, shapes or finishes.

Can it really be 20 years since Martin released John Mayers first signature model? Well, a look at the records sais yes.
To celebrate the anniversary of John's outstanding signature OM-28JM Martin, in addition the OMJM-John Mayer 20th Anniversary Model, which is far more similar to the regular OM-28JM, Martin release a showpiece model – the OM-45 John Mayer Anniversary.
OM-45 stands for the finest build and wood quality: abalone purflings along the top, back and sides (usually the headstock and fingerboard as well – we'll get there later). But this is no ordinary OM-45 – of course there is no such thing as an ordinary OM-45, but this one is even less so. To begin with there is the choice of wood: Like the OM-28JM this guitar has an Engleman Spruce top for an extra full tone. Back and sides are made of glorious Guatemalan rosewood, which is nowadays used as a replacement for the barely obtainable Brazilian rosewood.
John's first signature Martin featured aluminium borders around the headstock and bridge. Now Martin take this concept two steps further. First the metal is upgraded to finest silver. Second, the border is expanded to the fretboard and pickguard. These silver ornamentations are a perfect match for the guitar's very special Gray Sunburst finish – a paint job that is far too rare and makes this instrument even more outstanding.
The label features the signature of John Mayer.
