The Tama HP900PSW dual kick pedal is a part of Tama's extremely popular
Iron Cobra drum pedal family. Thanks to its innovative "Cobra Coil"
pedal spring, the HP900PSW gives you an incredibly smooth and fast
response, as the Cobra Coil quickly returns the footpedal to its
original position after each kick. In addition to the Cobra Coil, the
HP900PSW features Tama's double-chained Power Glide Cam, for increased
power and speed. Other patented technologies - from a Vari-Pitch Beater
Holder to a Quick-Hook spring attachment are on-board the Tama HP900PSW
drum pedal.
Features

Power Glide Cam
The
best-selling Iron Cobra of the series, the Power Glide features a
double-chained offset cam which increases power and speed as the beater
reaches the end of stroke.

Cobra Coil (US.PAT.NO.7408104)
Until
now, the only way to adjust your beater stroke action was to tighten
the pedal spring. Sometimes that did the job. More often the action just
felt sluggish and heavier. TAMA's latest innovation, the Cobra Coil
simply and easily solves the problem. A special steel spring quickly
returns the footboard to its original position so the feel of Iron Cobra
becomes even more unreal. Even better, the Cobra Coil can be adjusted
to different positions on the new Iron Cobra footboard base plate.

Cobra Pedal Housing
Iron
Cobra pedals come equipped with nylon insulators for the bearing
housings inside the pedal frame. The insulators keep the bearings
centered in place and secured in the most stable position. This ensures
proper bearing support for the drive shaft without unnecessary stress.
The end result of these improvements is the smoothest pedal action
possible.

Speedo-Ring
TAMA
eliminated another source of friction by replacing the traditional
nylon rocker cam with the Speedo-Ring, a rocker cam with a high quality
built-in ball bearing rocker.

Oiles® Bearing Hinge (US PAT.NO.6100460)
Offering
even less friction than standard ball bearing, Oiles® bearings also
eliminate side-to-side motion and provide superior durability (which is
why they're used in the aerospace industry).
(Oiles® bearings is a registered trademark of the Oiles Co.,Ltd.)

Spring Tight (US PAT.NO.5365824)
Twisting
springs severely reduce pedal smoothness. Spring Tight, a clever
half-moon shaped spring tension rod, keeps the spring from twisting so
there's never any loss of power transmission.

Iron Cobra Beater (US PAT.NO.5317946)
The
Iron Cobra beater adjusts the beater head angle to guarantee a flat hit
to the bass drum head every time, translating your strike into maximum
power. In addition, it's easy to obtain different bass drum sounds
simply by changing the beater head.

Vari-Pitch Beater Holder (US PAT.NO.5297467)
Vari-Pitch
beater angle adjustments are completely independent of footboard angle.
The Speedo-Ring allows you to adjust the angle of the footboard link
independently of the beater angle. And with the combination of the
Speedo-Ring and the Vari-Pitch, you can achieve any kind of stroke and
also enjoy improved playability.

Para-Clamp II (US PAT.NO.6011208)
Para-Clamp
keeps your pedal flat on the floor no matter what your bass drum angle.
The Para-Clamp is tightened from the side so you never have to insert
your finger under the footboard. And since you can clamp your pedal to
hoops up to 14mm (9/16") in thickness, Iron Cobra will fit just about
any bass drum in the market.

Tight Lock
Tight Lock makes sure the beater shaft stays put by fixing and locking the square head bolt which fixes the beater shaft.

Pedal Anchor
To
keep left-side double pedals from walking, a special stabilizer is
mounted to the outside frame. This augments the stability of the floor
anchor bolts.

Quick-Hook (US PAT.NO.6137040)
Quick-Hook
not only allows rapid spring attachment and reattachment for rapid set
up and tear down, it also eliminates wobbling and allows maximum power
transmission to the Speedo-Ring. And you never have to worry about it
slipping off during performance.

Connecting Rod (US PAT.NO.5994635)
The
Aluminum made connecting rod has made the light weight and smooth
adjustment possible. Instead of the screws fixing the inner rod
directly, the small plate inside spread the pressure appropriately and
tightens more securely without damaging the rod. Also the new design
prevents the inner rod coming off from the outer while adjusting the
length, which reduces the trouble during setup and teardown.

Carrying Cases (US PAT.NO.D438006)
You
know what pedals go through night after night. After being stomped on
over and over, they get thrown in bags and road cases where there's more
hard rock and roll than the gig itself.
That's why precision instruments like our Iron Cobras come with a
specially designed protective carrying case. It's amazing no one thought
of it before.
