14. The Martin D-45
As an acoustic guitar, the Martin D-45 is considered the Pearl or “the Flagship of the Martin Line.” Neil Young and Gene Autry have played on this and the rest, as they say, is history. Abalone is what the trim and fretboard are made of which is why the name “pearl” is given to this acoustic guitar. 91 of these D-45s were created in total, but if you can get hold of one, you’ve got yourself a dream guitar.
