C. F. Martin & Co. has been family owned and operated since the first guitar came off Christian Frederick Martin Sr.’s first workbench in 1833. As of 2022, there have been 2.5 million guitars produced. In honor of this milestone, the instrument design team offers one of its most stunning masterpieces – the Custom D-2.5 millionth – which will live in the Martin Museum in Nazareth, Pa. The entire theme of the guitar represents Christian Frederick Martin Sr.’s transition from Germany to America.
