Neck and Headstock

Neck Species
The neck of the Jackson Browne Signature Model is constructed from one solid piece of quarter-sawn, lightweight mahogany. The luthiers in Gibson Montana's Acoustic Master Shop carefully select the grain orientation of the mahogany used for necks to optimize tone and sustain. Neck Species
Tonal Characteristics
The wood, construction, and headstock pitch all contribute greatly to the superior resonance, sustain, and overall tone of the Jackson Browne Signature Model.
Neck Profile
The neck of the Jackson Browne Signature Model is carved to a modified "V" profile, as specified by the artist himself. Its specific design can be described as offering slender playing comfort combined with the touch of a V shape for a classic Gibson vintage feel. Neck Profile
Gibson uses a compound dovetail joint fixed with hot-hide glue to attach the neck of the Jackson Browne Signature Model to the body at the 12th fret. This technique, traditional in cabinet making and high-end luthiery, creates a joint with superior strength to that of a single piece of wood and transfers maximum string and neck vibrations into the resonant and deep body. Neck Joint
Headstock Angle (Pitch)
The Jackson Browne Signature Model's headstock is carefully angled at Gibson's traditional 17 degrees. This subtle yet crucial element of the guitar's design increases pressure on the strings and helps them stay in the nut slots. An increase in string pressure also means there is no loss of string vibration between the nut and the tuners, which equals better sustain.
Truss Rod
Gibson's traditional truss rod, found in nearly all of our guitars, is highly responsive to the individual adjustments you'll want to make to personalize and optimize string action and sustain. Truss Rod
The classic block Gibson logo is inlaid in mother-of-pearl across the top of a traditional advanced jumbo-style headstock. Logo
Joint Angle
3° (+/- 15 seconds)
Hot-hide glue is used to attach the dovetail joint, which is the traditional glue used to construct many of the greatest acoustic guitars of the 20th century.
Fingerboard and Nut

Fingerboard Species
The Jackson Browne Signature Model's bound fingerboard is made from select rosewood, the traditional wood used for this model.
The frets are made from Gibson Montana's standard fret wire, a medium-jumbo wire made from a nickel alloy for excellent tonal clarity. Frets
Tonal Characteristics
Rosewood fingerboards have been a favorite for more than a century and are legendary for their rich, round tone, attributes that blend beautifully with the depth and dimension of the Jackson Browne Signature Model's voice.
Gibson's traditional 12" fingerboard radius is used for this guitar, which offers excellent comfort for both chording and single-note runs, and avoids any "choked-out" notes when strings are bent for blues, country, and rock playing.
The fingerboard of the Jackson Browne Signature Model carries abalone slotted-diamond inlays. Inlays
Nut Width
The width of the nut on the Jackson Browne Signature Model is approximately 1.805", which affords the space demanded by fingerstyle players.
Nut Material
The Jackson Browne Signature Model carries a genuine bone nut, a traditional component of quality flat-top acoustic guitars. Nut Material
