Neck and Headstock

Neck Species

Tonal Characteristics
A hand-fit, compound dovetail neck joint transfers a maximum of resonant energy from that big mahogany neck to the body. The Aaron Lewis Southern Jumbo is crafted from all angles to get you heard in premier style.
Neck Profile
The guitar’s neck is carved to a custom Aaron Lewis-designed “V” profile. Neck Profile
Tolerance
When fitting the neck and body together, we take advantage of our precise measuring equipment so that all angles, pitches and alignments maintain a tolerance within .005 of an inch. Not only does this help to keep your guitar in tune but it also maintains proper string alignment relative to the fingerboard.
Joint
The Aaron Lewis Southern Jumbo’s neck, which is secured with hide glue, is attached with a compound dovetail joint, positioned at the 14th fret.
Headstock Shape and Angle
The guitar’s headstock is carved in the style of Gibson’s CF-100 and is pitched at the vintage-correct 17-degree back angle. Every Gibson headstock is carved out of the same piece of mahogany as the neck, then fitted with Gibson’s traditional wing blocks.
Truss Rod
Gibson’s traditional truss rod, found in most 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
