The grand concert body shape of the AC340OPN, along with Thermo Aged Mahogany top with Thermo Aged spruce X bracing and shorter scale delivers a wide, dynamic sound when strumming, quick response when fingerpicking, thanks to the lightweight open-pore natural finish. Mahogany top/back/sides body construction creates rich, bright and balanced tonal character, while the tortoiseshell body binding gives this guitar a true vintage vibe. The mahogany soft-V shape neck in satin finish with a rosewood fretboard provides playing comfort. Open-gear tuners with butterbean knobs (18:1 gear ratio) ensure accurate, stable tuning and help reduce the headstock weight, while bringing vintage vibe in its looks. A bone nut and saddle are chosen for its ability to transfer the string vibration naturally. D'Addario Nickel Bronze strings emphasize the natural voice of Thermo Aged wood with incredible clarity, resonance and projection.

Artwood Vintage Series
The "modern approach to acoustic guitar tradition" has long been Alvarez's catchphrase for the Artwood series. Artwood Vintage steps even further back in history and borrows the best features of highly desired vintage instruments.

The Artwood Vintage series now showcases another vintage element by applying an "aging" process to the tonewood—"Termo Aged" tonewood, made by a special drying process at a high temperature which is commonly known as "baking" or "torrefaction." Only choice selected and seasoned tonewood can be cured to Thermo Aged wood. The wood is heated in a vacuum with a specific recipe for each kind of the wood in order to release water and decompose resin contained within the wood. As a result, Thermo Aged tone wood becomes light, hard and stable like tone wood dried for decades, while providing amazing response and a louder sound. The tone character includes a full-bodied low-end and a great smooth sustain in the treble strings which are common features of vintage guitars.
