Frank Brothers Sonar NAMM 2026 Show Piece | Nicotine White (1 of 1)

The Sonar is that rare kind of guitar that feels like it’s already been yours for years the first time you pick it up — familiar, inspiring, and impossibly comfortable. Built around a classic 25.5” scale, a narrower 1.65” nut, and a smooth 9.5” radius, it delivers that unmistakable “California” feel: fast under the fingers, responsive to every touch, and endlessly expressive.

At the heart of this instrument is its stunning cocobolo neck and fretboard — a feature usually reserved for the very highest-end boutique builds. Cocobolo isn’t just visually striking with its deep, complex figuring and natural warmth; it’s also prized for its density, stability, and tonal richness. The result is a neck that feels incredibly smooth and solid in the hand, while adding sustain, clarity, and a subtle sweetness to every note. It’s the kind of wood choice that immediately sets this guitar apart.

Deep vintage-style contours wrap naturally against your body, making long sessions effortless and addictive. Whether you’re digging in with authority or backing off for subtle nuance, the Sonar responds with balance, depth, and character — enhanced by the resonance and articulation that cocobolo brings to the instrument. It’s the kind of guitar that disappears in your hands and lets the music take over.

Finished in beautifully aged nitro with tasteful relic work, every detail feels intentional — from the premium hardware to the organic, lively response of the body and neck. This is not a mass-produced guitar chasing trends. It’s a thoughtfully crafted, boutique instrument built for players who appreciate exceptional materials, refined feel, and real musical connection.

If you’re looking for a guitar that blends vintage soul with modern playability — elevated by a rare cocobolo neck and fretboard — something that feels broken-in, personal, and deeply inspiring, the Sonar delivers in every way. This is a lifelong player’s instrument.
