In taking an entirely fresh approach to lug design,
our craftsmen have come up with an ideal design
that delivers greater sound performance and
convenience. These new lugs hook onto bolts that
are attached to the shell, which allows the lug
casings themselves to "float" eliminating any direct
contact between the lug and the shell. As this design
reduces the amount of hardware actually attached to
the drum shell, the shell is allowed to vibrate freely. On an 11-inch shell the lug bolts, as well as
the YESS mounting system, are all attached to the shell at its nodal point to greatly minimize
influence on shell resonance to deliver maximum tone.
Another benefit these lugs provide is when it comes time to change the head, it is no longer
necessary to remove the tuning bolts from the lugs to remove the hoop. Just loosen the bolts
enough to slide the lugs off of the bolts and the hoop comes right off. No more lost washers, etc.
and head changes can be done quicker and easier than before.
* Nodal point mounting is patented by the Nobel & Cooley Drum Company.
The new claw design found on the
Absolute drums offers quick tuning,
smooth head changes, and noise free
performance. The tuning bolt utilizes a
wing type bolt that aids in tuning the bass
drum. Inside of the newly designed zinc
die cast craw is a plastic ring insert that
keeps the bolt from loosening and falling
off. The inner side of the claws is given a
plastic covering that prevents noise and
offers protection to the hoop from
damage.

Absolute lugs that were offered on
earlier models are also available.
