Wood Shells
The sound of any drum starts with the shell. The creation of all Yamaha shells starts with the selec-
tion of the fi nest materials possible. Excellent woods are carefully selected and cut into plies and
sealed together precisely with evenly distributed air pressure using our Air-Seal System. As a result
every shell created with this process is in round and of uniform thickness to an incredibly perfect
degree, and produces superior tone quality with exceptional durability.

Wood Hoops
Our 19-ply vintage wood hoops are crafted
from select maple, specially coated with ure-
thane for maximum durability. Wood hoops
promote an organic sound characterized by
good sustain. Rim-shots gain solidity and
power simply not found with other hoops.
Metal Shells
Every Yamaha snare drum is in round and has a fi nely honed edge and carefully shaped snare
bed. Steel shells are 1.2mm thick; brass and copper shells are 1.5mm thick; and aluminum shells
are set at 2.0mm.
Brass shells deliver a rich, colorful tone with well-balanced defi nition through the dynamic range.
Some say that brass lies between steel and wood in timbre. Versatile enough for concert settings,
copper shell snare drums are characterized by sharp attack and strong low frequency response.
Steel shell snare drums exhibit strong attack, a bright tone, and long and sustaining rim-shots.
Aluminum shells offer a light, clean, and dry tone with plenty of body.
Metal Hoops
The design and composition of the hoop play an impor-
tant role in the sound of the snare drum, especially when
executing rim-shots. Yamaha employs three types of
metal hoops (steel, aluminum, and zinc) and two different
manufacturing processes (roll forming and die-cast) in
the production of four different hoop styles(see character-
istics chart below).
The standard 1.6mm steel hoop can be used in all situ-
ations for a wide-open sound. The 2.3mm Dyna Hoop
offers a sharper response and more solid rim-shots. Our
3.0mm zinc die-cast hoop fi rmly anchors the drumhead
and delivers penetrating, full-bodied rim-shots. The
3.0mm Aluminum Die-Cast hoop provides many of the
attributes of the Zinc hoop but without the extra-weight.
Rim-shots are slightly more open, while attack and decay
are magnifi ed. Aluminum Die-Cast and Zinc Die-Cast
hoops fi x the head securely on the bearing edge. This
precise head seating promotes natural tone and mini-
mizes sound loss.
Wood Hoop Waves
The power spectrum decreases smoothly from low frequency to high frequen-
cy ranges. Harmonic sounds are rich in middle frequency range (300-600Hz).
Die-cast Hoops Waves
The power spectrum is low in middle frequency range and harmonic sounds
in high frequency range (600-2,000Hz) is outstanding.
