Why We Love This
Here's one of our recent Martin Custom Shop takes on a D-18 (essentially, a Standard Series D-18 upgraded with a European Spruce top). This guitar was sold earlier this year, and traded back in when its owner decided an electric instrument was the priority. It remains in excellent condition, with barely any evidence of prior ownership. Priced with its original hard case.
