This is a special run of Martin GPC16 style guitars designated as GPC14F. Spruce top and rosewood back/sides. Ebony fretboard. Fishman MX-T preamp and built in tuner. Made in USA. This is an upgrade from the only other acoustic I've ever owed and still own. That being a Takamine EAN40G. I love the tone the Takamine and will hang on to it. But it's starting to show signs of its aging. So this Martin will likely become my #1 workhorse acoustic after some bonding time with it. Look for some sound samples in an upcoming recording soon.
