This 2017 Martin 0000-18 Gruhn Spec brings something unique—wider nut, thicker neck, and a body size that splits the difference between comfort and horsepower. It’s in great condition with just a few signs of honest use. The tone is sturdy and focused, but with a lushness that keeps it from ever sounding boxy—think clarity with some warmth in the corners. The neck carve and nut width make for a unique feel that’s hard to go back from once you settle in. A smart, no-frills take on the 18-style inspired by George Gruhn. Comes with the OHSC.
