Yamaha TAS1E Ultra Marine: Acoustic-electric innovation with onboard effects

The Yamaha TAS1E Ultra Marine is an advanced acoustic-electric guitar crafted for players who want inspiring sound and minimal external gear. Yamaha’s TransAcoustic System70 technology is paired with a solid spruce top and mahogany back and sides, creating a blend of natural resonance and digital effects. The eye-catching Ultra Marine finish and concert body shape set this model apart visually and sonically. Designed for seamless transitions from unplugged sessions to live performances, it delivers built-in ambient effects and modern playability.

Standout Features: Immersive effects without external gear

TransAcoustic System70 gives players reverb and chorus that resonate through the instrument’s body—no amp or pedal required. Ambient textures are easy to dial in with onboard controls, providing atmospheric tones wherever you play. Plug in via line out and maintain effects on stage or in the studio.

Premium tonewoods and comfortable playability

Superior tone relies on solid spruce and mahogany, known for projection and warmth. The concert body is responsive and ergonomic, and a walnut fingerboard with mahogany neck enhances playability during longer sessions.

• Top: Solid spruce — produces a bright, clear tone and wide dynamic range
• Mahogany back and sides enrich the midrange for a warm character
• Neck: Mahogany — comfortable profile for effortless fretting
• Fingerboard: Walnut — smooth feel supporting agile movement
• Body shape: Concert — designed for comfort and articulation

Modern electronics and built-in effects for creative performance

Two reverb types (room and hall), chorus, and line out volume are all accessible directly on the guitar, allowing instant inspiration for practice, songwriting, or performance. Yamaha’s actuator system projects these effects acoustically, and their character remains when plugged into an amp or PA.

• With TransAcoustic System70 electronics, reverb and chorus come from within the instrument
• Controls: Onboard reverb, chorus, and line out volume
• Pickup system: SRT Piezo for consistent sound when amplified

Player-focused hardware and stage-ready features

Stability and reliability are ensured through die-cast chrome tuners and a durable walnut bridge. The softshell case is included for protection and easy transport. Robust construction supports years of dependable performance.

• Bridge: Walnut for tonal clarity and long-term durability
• Tuners: Die-cast chrome — keep tuning precise and stable
• Strings: Elixir NANOWEB 80/20 Bronze Light (.012–.053) for balanced feel and extended lifespan
