Faith FKN Naked Neptune Baby Jumbo Acoustic Guitar - Mahogany/Spruce

Big on tone, light on frills—the Faith FKN Naked Neptune Baby Jumbo is a stunning all-solid acoustic that strips things back to the essentials: raw tone, natural feel, and exceptional playability. Crafted with care and designed for expressive performance, this guitar blends refined tonewoods and a comfortable, compact body shape into a serious player's instrument.

Part of Faith’s Naked series, the Neptune takes on a Baby Jumbo shape, offering the projection and power of a jumbo without the bulk. The body is all-solid, with a solid Engelmann spruce top delivering rich, articulate highs and fast response, paired with solid Indonesian mahogany back and sides for warmth, balance, and low-end depth. The result is a voice that’s bold yet nuanced, perfect for everything from delicate fingerstyle to percussive strumming.

The natural satin finish lets the tonewoods breathe and resonate freely, while giving the guitar a minimalist, earthy aesthetic. No gloss, no bindings—just the honest look and feel of beautifully resonant wood.

The mahogany neck offers a familiar, slim profile, and is topped with a smooth rosewood or ebony fretboard with a 16" radius and 43mm nut, making it a joy to play whether you're flatpicking or fretting complex chord shapes. A 12th-fret ‘F’ inlay and an abalone rosette offer subtle but tasteful visual touches that match the guitar’s understated elegance.

Whether you're recording in the studio, performing live, or just playing for yourself, the Naked Neptune offers inspiring tone, effortless playability, and solid reliability in one beautifully built acoustic. 

If you're seeking a high-quality acoustic with character, clarity, and comfort—without the over-the-top price tag or cosmetic clutter—the Faith FKN Naked Neptune is your perfect match. A favourite at Musicmaker for players who value pure sound and playability above all else.
