Back Contour
Eliminating the contoured back found
on prior models increases the volume
of wood in the body to deliver a woodier
tone.
Body Contour
The new SG has a more pronounced
arch compared to the earlier SG
models. Regulating the balance in the
maple top’s thickness enhances mid
to low-end tone and delivers smoother
distortion.
Small Head Design
B a l a n c e h a s a g re ate r e f fe c t o n
p l aya b i l i t y t h a n we i g h t. U s i n g a
design that is smaller and lighter than
conventional heads moves the center
of gravity closer to the body, improving
playability.
Grover Locking Tuner
Locks strings in place at the tuner’s
string post. Prevents pitch problems
due to tuning peg slippage and makes
speedy string replacement possible.
Lightweight, sleek design does not
affect instrument sound or playability.
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
ngerboard, 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
fi
nish and wood are release by
applying speci
fi
c vibrations to the completed guitars. Once this treatment 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.
Since its spectacular debut, Yamaha SG series guitars have accompa-
nied many a musician on their road to success. From its rich tone and
long sustain to its superior performance and re
fi
ned design, all of its
signature characteristics have stood the test of time, remaining relevant
to this day. Trends and special requests by musicians over the last
30+ years have resulted in numerous spec changes and the release of
special models. And while the latest SG3000/2000/1000 guitars look
the same as the original, there are many re
fi
nements that improve upon
their perfection.
Over the course of the SG’s history, these three new SGs, the
SG1820/1820A/1802, represent the most dynamic approach yet. Look-
ing at current trends in music and the sound requirements of today’s
guitarists, we have taken three approaches to sound
SG1820:
Modern rock sound. All-around instrument delivers a clear, rich
low-end tone capable of everything from clean cutting tone to distortion.
SG1820A:
Designed for the next-generation guitarist. Delivers a beautiful
hard distortion and releases an intense sound from its sharp styling.
SG1802:
Sound, looks, classic styling, its all there in this model. The
combination of wide single coil pickups and SG body deliver a warm,
clear tone.
The new SG also features a wide variety of re
fi
nements including hard-
ware modi
fi
cations. A new page in Yamaha’s SG history starts here.
