The sheer acoustic character driven by this concert-style instrument comes down to a tried-and-true pairing of tonewoods that yields a beautifully transparent, organic voice before any technology even gets turned on. Yamaha built this guitar around a solid spruce top matched with mahogany back and sides, creating a highly resonant acoustic profile that balances crisp, bell-like high-frequency response with a dry, punchy midrange and zero muddy low-end build-up. Because of the slightly more compact concert body dimensions, chords stay remarkably tight and cohesive, while single-note lines possess a clear, immediate separation that sits perfectly underneath a live vocal mic or tracks cleanly during a close-mic studio session.

The actual physical layout is focused entirely on a fast, fluid playing experience that keeps muscle fatigue down during long writing sessions or late-night practices. The mahogany neck sports a smooth matte finish and a comfortable profile that fills out the hand naturally, running down to a unique walnut fingerboard with a generous 15.75-inch radius. A player-preferred 1.73-inch nut width gives both fingerstyle stylists and flatpackers plenty of real estate for clean articulation across all 20 frets, while robust die-cast chrome tuners up on the headstock make fine-tuning predictable and exceptionally stable. The action arrives low and effortless, eliminating any resistance so your musical concepts translate directly onto the fingerboard without any physical fight.

Visually, this second-generation TransAcoustic instrument maintains a clean, traditional silhouette that values classic acoustic design over modern gimmicks, treating the gloss top to an elegant, stylized soundhole rosette and sleek black body binding. But hidden away on the inside is an absolute game-changer: Yamaha’s proprietary SYSTEM70 TransAcoustic technology. An internal actuator is installed directly to the inner surface of the back wood, turning the entire acoustic chamber into a physical speaker. When you adjust the low-profile, space-efficient control buttons on the upper bout, rich, authentic reverb and chorus actually radiate straight out of the soundhole into the room around you without plugging into a single pedal or external amplifier. When it is time to plug into a PA or soundboard, the under-saddle piezo pickup translates your pure acoustic tone and ambient effects directly into a line out with zero hassle. Wrapped up safely in a heavy-duty hard bag, the TAS1-E is an inspiring, self-contained performance machine designed for musicians who want massive acoustic flexibility without the footprint of heavy external gear.
