A faux tortoise pickguard and antique white details complete the look, creating a guitar that feels at home in recording studios and on stage.

Black Walnut Back and Sides Shape Distinctive Sound

Domestic black walnut forms the back and sides, giving this acoustic guitar a unique tonal character. Walnut produces clear mids with tight lows and articulate highs, resulting in a focused, balanced sound profile. The wood's natural grain also adds visual appeal, highlighted by a gloss finish. Players who need clarity for recording or live performance will appreciate the way walnut brings subtle detail forward, especially in complex chord voicings.

Spruce Top and Scalloped X-Bracing Increase Resonance

A solid spruce top, supported by scalloped X-bracing, helps the guitar respond quickly to picking and strumming. The bracing allows the top to vibrate more freely, creating an open, dynamic sound. Spruce is known for delivering volume and brightness without losing warmth. This combination lets players explore gentle fingerstyle or heavier rhythms while still getting a clear, consistent output.

Comfortable Modified Low Oval Neck Enhances Playability

Mahogany shapes the modified low oval neck, making it easy to move between frets. The short 24.9" scale length reduces tension, helping fingers glide over the ebony fingerboard with less fatigue. Grover nickel vintage tuners offer reliable stability for tuning adjustments. A modern belly bridge keeps string spacing consistent for accurate chord formation and smooth transitions.

Durable Materials and Gloss Finish Add Longevity

Every detail of this acoustic model supports lasting use. Gloss finish on all surfaces protects the woods from moisture and wear. Bone nut and saddle improve sustain and string clarity. European flamed maple bindings and antique white accents reinforce the edges, while the dovetail neck joint adds structural integrity. A hardshell case provides safe transport for gigs or travel.
