Martin Custom Shop Craftsmanship Serving the GP Format
Made in Nazareth, Pennsylvania, this Custom Shop model embodies Martin's lutherie tradition applied to the GP format, known for combining the projection of a dreadnought with the balance of an OM size. Every detail-from wood selection to ornamentation-is designed to offer a unique piece, both a stage instrument and a collector's guitar.
Who Is This Guitar For?
Ideal for intermediate to expert guitarists seeking a responsive and precise acoustic. The flamed mahogany highlights fingerstyle, folk, blues, pop, and vocal accompaniment. Its balanced response facilitates studio work and microphone capture to preserve the richness of the natural tone.
Sound Characteristics
Flamed mahogany delivers a bright attack, a dense midrange, and tight lows, with a measured brilliance that enhances note articulation. The GP format ensures strong projection without excess, while the Sitka spruce bracing supports the top for greater dynamics and clarity. The Modern Belly bridge optimizes vibration transfer and intonation, and the ebony fingerboard enhances precision and sustain.
Recommended Compatible Accessories
To get the best from this all-solid wood acoustic, we recommend phosphor bronze steel strings in Light gauge (12-54) or Custom Light (11-52) depending on your playing style, a GP format hard case for perfect protection, a humidifier suitable for solid wood guitars, and a standard radius acoustic guitar capo.
