Ibanez AC340-OPN Artwood Thermo Aged Acoustic Guitar with Solid Mahogany Top

The Ibanez AC340-OPN Artwood is a comfortable Grand Concert acoustic that blends classic looks with modern playability. With its solid Okoume top, Thermo Aged Ovangkol bridge and open pore finish, it delivers a warm, woody voice with impressive resonance and a naturally responsive feel under the fingers.

Designed for players who value nuance and dynamics, the AC340-OPN excels at fingerstyle, light strumming and intimate songwriting sessions. A slightly shorter 634 mm scale and wider 45 mm nut offer an easy, relaxed playing experience, while quality components like a bone nut and saddle and Ibanez Advantage bridge pins help the guitar ring clearly and stay stable over time.

Warm, Responsive Solid Okoume Top

The solid Okoume top is the heart of the AC340-OPN, providing a full-bodied, warm midrange with a bright, articulate edge. Because it is solid rather than laminated, the top responds more directly to your touch and will continue to open up and develop character the more you play it.

Comfortable Grand Concert Body

The compact Grand Concert body shape makes this guitar easy to hold whether you are sitting or standing. Its balanced proportions and shallower depth help reduce fatigue during longer sessions, while still offering enough projection and clarity for confident strumming and detailed fingerpicking.

Thermo Aged Ovangkol Bridge and Maple Bridge Plate

Ibanez use their Thermo Aged process on the Ovangkol bridge and maple bridge plate, carefully drying the wood to make it lighter, harder and more stable. This enhances resonance and improves the transfer of string vibration into the body, giving you stronger lows and low mids with a more mature, played-in acoustic tone.

Player Friendly Neck and Ovangkol Fretboard

The Nyatoh neck with Ovangkol fretboard offers a smooth, comfortable feel and a rich, mid-focused response. The 45 mm nut width gives your fretting hand a little extra space for clean chords and intricate fingerstyle patterns, while the 400 mm radius keeps things familiar and easy to navigate across all 20 frets.

• Solid Okoume Top - A solid Okoume soundboard delivers a warm, woody midrange with a clear, bright top end. The solid construction responds dynamically to your playing and will age gracefully, rewarding regular use with an increasingly open and resonant tone.
• Grand Concert Body Shape - The Grand Concert body is compact and comfortable, ideal for home playing, recording and acoustic sessions. Its focused projection and balanced response suit fingerstyle, light strumming and more delicate arrangements where clarity matters.
• Thermo Aged Ovangkol Bridge and Maple Bridge Plate - The Thermo Aged Ovangkol bridge and maple bridge plate are specially treated to be light and rigid, improving stability and resonance. This helps the guitar produce stronger lows and low mids, giving your chords and single notes extra depth and presence.
• Bone Nut, Compensated Bone Saddle and Ibanez Advantage Pins - A bone nut and compensated bone saddle promote excellent sustain, tuning stability and clear note definition across the neck. Ibanez Advantage bridge pins make string changes quicker and more secure, with a bulb-shaped end that is easy to grip and helps keep strings firmly in place.
