Martin Custom J-28 Style - Spruce/Koa
This Round Hill Music Co. spec'd Martin utilizes absolutely exceptional, hand-selected, broad figure koa for the back and sides creating not only a visually striking appearance, but also a balanced tone with a strong midrange, bright highs, and tight, controlled bass. Koa will become warmer, richer, and more complex over time as it ages is played more.
The Martin "J" body is a large jumbo-style acoustic guitar shape with a wide lower bout and a rounded outline with a pronounced waist. It is bigger than a Dreadnought, giving it more internal air volume and a fuller visual profile. The design is meant to produce strong projection and deep bass while maintaining a clear, balanced tone.
The GE Modified Low Oval neck profile is a comfortable, modern neck shape inspired by Martin’s Golden Era (GE) vintage designs. It has a low-profile oval back that feels relatively slim in the hand, but with slightly fuller shoulders than the standard Modified Low Oval, giving it a bit more substance and support.
