Answers: What is it like to play a custom 12-fret acoustic guitar with a single-O body?

• Acoustic guitar design
• 12-fret vs 14-fret guitars
• String spacing at the bridge
• Adirondack spruce and rosewood acoustic guitars
• Custom acoustic guitar build

What it concludes

• A 12-fret guitar shifts the neck and bridge more toward the center of the lower bout, creating a rounder, mellower, and sweeter tone.
• A single-O body shape offers less bass and volume than a dreadnought, but fills the room cleanly and provides excellent balance between single notes and chords.
• Adirondack spruce tops are brighter and louder with more dynamic range and respond exceptionally well to light picking.
• A slot-head headstock increases the breaking angle of the strings across the nut, pressing them down harder for a distinct effect on the sound.
• A custom acoustic guitar with a traditional neck carve, narrow string spacing, and comfortable body shape can exceed expectations for playability and tone.
