When TromboneBuddy™ was conceptualized, a core requirement was that it absolutely must not make
the instrument harder to play. This was a deal-breaker and meant it had to be as light and compact as
possible, and specifically, could not make the slide‘s action slower.
To be truly useful, it also needed tough enough to withstand some abuse.

Carbon fiber, by it’s nature is extremely light and stiff. Depending on the variety, the tensile modulus of
carbon fibers can be 2-10 times that of steel! It’s no wonder why so much is in use in the aerospace
industry as well as in Formula1 race cars, and was the first choice material for TromboneBuddy™.

Tactile position marking
In order to generate enough magnetic flux to be felt, while being small and light as possible, the highest
available grade of neodymium magnet is used. There is easily enough magnetic force available in the
mechanism to distort most lightweight structures, and cause an unacceptable braking effect between
the magnet guide and position marker tube.

TromboneBuddy™ was designed with a patented triaxial magnet guide which uses miniature ball
bearings to unload these significant resistive forces.

The result of this elegant engineering is an extremely nimble and fluid feel to the device, while each
position has a distinct and precise notch feeling.
