| Developed by Vicente Honorato of Stomvi in 2008,
these are the "Rolls Royce" of valve
guides. They are made of brass with plastic inserts
at the contact point with the spring barrel. This
makes them quiet like plastic but have the mass of
brass. They come with 2 sets of inserts; one set of
brass, and one set of copper allowing you to "dial in"
the amount of mass that works best for you.
They
are available for V~Raptors, VRII, and all other
Stomvi trumpets.
There are 7 different weight configurations
available to you ranging from 3 to 13.5 grams. Some
examples are listed below:
1. 3 grams with no inserts.
2. 9 grams with copper inserts.
3. 12 grams with brass inserts.
