A Custom Shop interpretation of one of Martin's most player-friendly body styles, this 2025 OM-18 in 1933 Ambertone is a thoughtfully appointed Orchestra Model built to vintage spec with premium modern execution. The solid, premium Adirondack spruce top over mahogany back and sides is the classic OM-18 formula — balanced, articulate, and remarkably responsive at lower volumes — and the 1933 Ambertone finish gives it a warm, aged amber glow that suits the vintage intent beautifully. Black ebony fingerboard and bridge are exceptional appointments at this level, contributing to the crisp note separation the OM format is known for. Featuring East Indian Rosewood binding, you won't have to worry about any separation issues in the future compared to other models with plastic binding. The GE Modified Low Oval neck profile (.818"–.909") is among the most comfortable Martin has offered, and the 1.767" nut width with 2 1/8" string spacing at the saddle strikes the ideal balance for fingerstyle and flatpicking alike. Grover nickel vintage button tuners with an 18:1 gear ratio complete the period-correct package. No modifications or repairs. Very good condition with original hardshell case.
