This guitar is a 2007 Martin HD-28, with rosewood back and sides and Sitka Spruce top. I recently installed a K & K mini pickup in it. I also have been blessed with a 2009 D-18GE, (golden era) with mahogany back and sides and a Adirondack Spruce top. I am about to carry the HD 28 to our weekly jam that I have been participating in since about 1990. I love acoustic music, bluegrass, gospel, jazz, some big band, all from way back in the day.
I hope this answers your questions.
Have a blessed day,
Leon
