Description

Adirondack Spruce Top With Forward-Shifted X-Bracing
An Adirondack spruce top paired with a forward-shifted X-bracing pattern drives the guitar's dynamic response. The braces, also crafted from Adirondack spruce, are set to allow more movement in the top. This construction produces strong volume and crisp articulation, making fingerstyle and flatpicking passages stand out. The system supports clear separation between bass and treble, adding definition to every note played.
Mahogany Back and Sides Shape a Warm, Focused Tone
Mahogany for the back and sides offers a distinct tonal character, known for warmth and direct sound. The wood's natural density helps tame overtones, creating a focused midrange that supports complex chord shapes and single-note runs. The gloss finish enhances durability while highlighting the deep color and grain, making this dreadnought visually striking and tonally balanced.
Modern Belly Bridge and Waverly Nickel Tuning Machines Streamline Setup
This acoustic guitar features a modern belly bridge made of ebony, set for precise intonation and string spacing. White bridge pins with faux tortoise dots add visual detail. Waverly nickel tuning machines keep the instrument in tune throughout long sessions, and the bone nut and saddle maintain solid contact for better resonance. The pickguard protects the top during aggressive strumming and adds a classic look to the body.
Quality Materials and Construction Support Longevity
Martin's dove tail neck joint, select hardwood neck, and gloss finish on the back and sides ensure lasting stability. The ebony fingerboard resists wear, and abalone Style 45 snowflake inlays add a touch of artistry. A hardshell case protects the guitar from impacts and climate changes. The bone saddle and nut, paired with premium strings, help maintain tone through years of use and travel.
