Ibanez AC340 Open Pore Natural — Warm Okoume Voice in a Compact Body

The Ibanez AC340 Open Pore Natural is a Grand Concert acoustic guitar that pairs a solid okoume top with okoume back and sides, giving players a warm, woody voice at a price that fits a first-instrument budget. The compact body shape sits comfortably against the player, making long practice sessions easier than a larger dreadnought. A thin open-pore finish lets the wood breathe and resonate more freely than a thick gloss coat.

What Sets the AC340 Apart in Its Price Class

What separates this model from other guitars at this tier is the Thermo Aged Ovangkol bridge paired with a Thermo Aged Maple bridge plate — a heat-and-pressure treatment that stabilizes the wood and adds resonance. Ibanez Advantage bridge pins are easier to grip and remove than standard pins.

Body Shape and Tonewoods — The Heart of the Tone

The Grand Concert body shapes this guitar's tonal character, with a semi-solid build pairing a solid top with layered back and sides.

• The Grand Concert body shape provides a compact, balanced feel with a clear midrange focus.
• Top: Solid Okoume — dense African hardwood with warm midrange and bright top-end
• Back & Sides: Okoume — woody warmth when fingerpicked, punchy high-mids when strummed
• Construction: Semi-Solid — solid top with layered back and sides
• Cutaway: No — keeps body resonance intact
• Finish: Open Pore — thin finish that lets the top vibrate freely

Neck and Playability — Built for Smaller Hands

Neck dimensions are tuned for comfortable chord work and lead playing, with a 634 mm scale that keeps string tension lower than a dreadnought.

• Scale Length: 634 mm (25") — shorter scale lowers string tension
• Neck: Nyatoh — rich mid-low end and stable playing platform
• Fretboard: Ovangkol — dense, smooth hardwood for comfort and warmth
• Nut Width: 45 mm — wide enough for fingerstyle, not stretched for chords
• Fingerboard Radius: 400 mmR — flatter radius suits strumming and lead lines; 20 fret

Hardware — Components That Punch Above the Price

Exceptional hardware components are used throughout, including genuine bone at the nut and saddle along with premium coated D'Addario strings.

• Nut: Bone — transfers vibration more efficiently than plastic
• Saddle: Compensated Bone — adjusts string length for accurate intonation
• Tuning Machines: Chrome Die-cast (18:1 gear ratio) — hold tuning reliably
• Bridge Pins: Ibanez Advantage — easier to grip and remove; Strings: D'Addario XTAPB1253 (.012–.053)

Targeting the Right Player

The AC340 is the right choice for beginner and intermediate players who want a smaller, comfortable body and a warm, vintage-leaning tone without paying step-up prices. Singer-songwriters chasing a James Taylor-style fingerpicking voice will appreciate the okoume's woody midrange, while students moving up from a starter dreadnought will find the Grand Concert shape easier to cradle. Players have a reliable stage or campfire instrument with stable tuning.

The Artwood Series

Inside the brand's Artwood series, the instrument blends traditional acoustic construction with modern tonewood choices. The range has long been a home for affordable instruments that borrow features from higher-tier models, bringing thermo-aged components and bone hardware into a bracket usually reserved for entry-level guitars.
