Bringing Back Lost Ambience;

Yamaha’s new proprietary Studio Response Technology (SRT) brings back the natural, ambient sound of an acoustic guitar, and it does it with the signal from the output jack. Using a sound modeling technique that utilizes data obtained through extensive analysis of four acoustic elements that are missing from conventional pickup systems— string and body resonance, ambience, vintage microphone characteristics, and professional micing techniques, SRT delivers a natural, studio-quality acoustic guitar tone. The same tone that, until now, was only attainable by professional recording engineers in the world’s finest studios is now easily usable by any player, on-stage or in the studio.Using a sound modeling technique that utilizes data obtained through extensive analysis of four acoustic elements that are missing from conventional pickup systems— string and body resonance, ambience, vintage microphone characteristics, and professional micing techniques, SRT delivers a natural, studio-quality acoustic guitar tone.

A sound that guitarists have long dreamed of is now a reality. 

SRT Functions
The new SRT system lets you choose from three different high-end mic types as well as two mic positions that let you use techniques similar to those used in a recording studio. The system provides a total of six setting patterns. Click the buttons below the photos to hear the differences between various sound settings.
The system also allows mixing of pickup and mic sound elements using the BLEND knob, and control of body resonance with the RESONANCE knob to create a wide range of rich, natural sounds.

Secret to Good Sound

The SRT system is powered by two AA batteries instead of the more common PP3. Using an internal circuit to boost the batteries voltage to 11V reduces distortion, even when the batteries are low, and creates a wider dynamic range. With traditional 9V designs, the voltage soon drops to 8V and gradually decreases from there (average operating voltage in a PP3 system is 7.5V). This lower voltage produces disadvantages such as unstable operation and distortion – especially noticeable with SRT’s studio quality tone. SRT’s power circuitry provides stable operation nearly up to the time battery power is depleted, giving you better tone for longer.
