The HD-28 Semiquincentennial commemorates 250 years of American independence—crafted by a company that has been part of America’s story for nearly 200 years. It features wood from the legendary Basking Ridge white oak, a 600-year-old tree that stood through the First Great Awakening and the Revolutionary War. George Washington’s troops drilled within view of its branches, and Washington himself is said to have picnicked beneath it with the Marquis de Lafayette. That historic white oak is incorporated into the endpiece, heelcap, and Liberty Bell headplate inlay—placing a tangible piece of Revolutionary-era history in your hands. Its reclaimed Sitka spruce top showcases custom artwork by Martin Artist Robert Goetzl. Limited to just 250 guitars, this special edition is built on the iconic HD-28 platform—celebrating the model’s own 50th anniversary this year while carrying the legacy of American independence forward in every note.
