The Yamaha TAS1 C TransAcoustic guitar delivers rich acoustic expression and built-in spatial effects without requiring external amplifiers, pedals, or extra hardware. Built around a concert cutaway body shape, this instrument combines a solid spruce soundboard with built-in reverb, delay, chorus, and wireless Bluetooth playback. It gives acoustic players, fingerstyle guitarists, and session musicians a self-contained workstation for writing, rehearsing, and live performance.
Onboard TransAcoustic Effects and Digital Processing
Yamaha TransAcoustic SYSTEM78 technology uses two internal actuators to convert string vibrations into acoustic effects directly inside the body. Reverb, delay, and chorus radiate organically from the soundboard itself, filling the room with spatial depth without plugging into an amp or external pedalboard. Four top-mounted controls keep adjustments simple, while the dedicated TAG Remote companion app allows deep parameter editing and effect customisation from your smartphone.
Solid Sitka Spruce and Mahogany Concert Body
At its foundation, the TAS1 C pairs a solid Sitka spruce top with mahogany back and sides in a compact concert configuration. The solid soundboard delivers bright attack, wide dynamic range, and clear note articulation, while the mahogany body adds warm mid-range frequencies and balanced resonance. The integrated body cutaway provides smooth access to higher frets, making the body well suited to intricate fingerpicking and expressive chord voicing across the entire fingerboard.
Bluetooth Audio Streaming and Battery Power
Integrated Bluetooth connectivity transforms the guitar body into a wireless speaker, allowing you to stream backing tracks, rhythm guides, or reference songs directly through the instrument. You can play along with recorded audio in real time for interactive practice sessions or solo acoustic sets. The system is powered by an internal rechargeable lithium-ion battery that provides up to 5.5 hours of continuous play time and recharges easily via a magnetic port on the body.
Playability, Neck Profile and Hardware
Crafted for comfortable long-duration playing, the mahogany neck features a smooth matte finish that prevents hand drag during rapid position changes. The walnut fingerboard provides clear note articulation across a 20-fret layout with a 15.75" (40.0 cm) radius. Open-gear chrome machine heads ensure precise tuning adjustment, while a walnut bridge and urea nut/saddle setup maintain consistent string spacing and vibration transfer across the 25.6" (65.0 cm) scale length.
