A rare Martin here - one out of six ever made, and the first owner for this one was the one and only Steve Earle!
Matt Umanov ordered these form Martin originally in the 1970s, and made a re-order later. These boast HD-28 body and D-45 neck with abalone inlays.
The guitar is super resonant. The top has one small crack that has been professionally repaired and stabilised. The overall condition is great,
OHSC and COA from Matt Umanov guitars with signatures.
