SRT Powered is a new system designed to recreate the body resonance of an acoustic guitar in a bodiless guitar. Yamaha developed SRT Powered, collaborating with recording artists to create a system tailored to the unique properties of the new SLG body and modelled after the tones of a high-end Yamaha acoustic guitar captured using a carefully selected microphone in a professional recording studio environment. By actually reproducing the sound of an acoustic guitar—right down to its natural sustain and decay—Yamaha lets guitarists experience the genuine body resonance, body tone and ambience of an acoustic guitar.

SRT Powered sound can even be mixed with the sound from the instrument's piezo pickups, allowing guitarists to be even more flexible in their creative endeavors.

Because the SLG can virtually reproduce the sound of a guitar recorded with a microphone, players are free from complicated procedures involved in mic-ing up a guitar when recording at home or in other settings.

Yamaha’s SLG features excellent durability owing to its solid body structure, so users do not have to worry about damaging the instrument when playing live or traveling.

Both the steel string and nylon string models are fitted with a duel action truss rod, allowing both convex and concave bow to be adjusted.
