IRA (Initial Response Acceleration)
If you’ve ever played another guitarist’s instrument and not been able to get the
same sound, it’s probably because you are playing a different style than what
the guitar is used to. After playing the same guitar for years, the guitar adapts to
the guitarist’s playing style. It takes time for a new guitar to adapt to your own
way of playing. Stress found between parts like
fi
nish, woods, body, neck,
fi
n-
gerboard, nut, bridge, etc., must be released before all of the parts can resonate
together as an instrument. It takes time and a lot of playing for this to happen.
Using IRA technology, stresses like those between the finish and wood are
release by applying speci
fi
c vibrations to the completed guitars. Once this treat-
ment is complete, the guitar responds accurately to the guitarist’s performance,
and produces sound more easily. It also shortens the time needed for the guitar
to adapt to your playing style. And it delivers excellent sustain.
When we designed the SBG2000 over thirty years ago, our goal was to create without
compromise, the best guitar possible. While its design was inspired by the instruments
existing at the time, our design team scrutinized each part and every function, rethink-
ing and redesigning each component to create all new, original designs for all body
parts, neck, pickups, bridge, circuitry, even strap pins.
Th
e result was a highly refi ned design, which delivered a high quality sound and rich
sustain that won high acclaim from renowned musicians worldwide, and a popular-
ity with guitarists that it enjoys to this day. While the SBG2000’s design focused on
maximizing sustain, the next instrument we designed, the SBG1000, focused more on
delivering attack and a rock oriented tone. A set neck delivered greater attack making
it highly popular among rock guitarists.
When we set out to design the top-of-the-line SBG3000, we drew upon the knowledge
and technologies gained from the SBG3000 and SBG1000 to pursue a tone that is
richer, more natural, and woodier. While the sustain plate was sacrifi ced in the pursuit
of this tone, we utilized a through-neck and T-Cross maple design, along with some
hidden details, to optimize body vibration. Th
e result is a fi ne instrument that delivers
a wealth of rich tone and sustain as well as top quality fi nish and looks.
All SBG series guitars are carefully craft ed one at a time by the highly skilled master
luthiers at Yamaha Music Craft —an elite workshop dedicated to producing our top-
of-the-line handcraft ed acoustic guitars and custom instruments. SBG series guitars
also undergo Yamaha’s exclusive Initial Response Acceleration—a process that is also
applied to our acoustic violins that matures the instrument quicker producing a
highly responsive instrument that sounds as if it has been played for years.
Th
is is just one conclusion in our pursuit of solid body guitar sound. Please take the
time to experience this superb, fully matured sound.
