GR
Flugelhorn Mouthpieces
Silky smooth sound that is
easily colored, precise crisp attacks, easy upper register, outstanding
intonation. GR Flugelhorn Mouthpieces feature all of these playing
characteristics, plus rims identical to their trumpet mouthpiece
counterparts for seamless horn changes! Try one to see what GR
Flugelhorn Mouthpieces can do for your playing!

FL Models
GR Flugelhorn Mouthpieces are
available with any GR Standard rim and cup diameter.
GR FL Model Flugelhorn
Mouthpieces are ideal for most flugelhorn models. They offer a fat
velvety tone, outstanding intonation, and an amazingly efficient upper
register.
GR Flugelhorn Mouthpiece
Backbores are balanced with each cup volume to produce a characteristic
flugel sound with precise intonation.
GR Flugelhorn Mouthpiece Cups
are designed to produce a full velvet like sound that can easily be
colored. These mouthpieces feature outstanding intonation, common to all
GR Mouthpieces, and a very easy upper register. |

|
FL*** Models
Similar to the FL models but with 10% more cup
volume! If you are looking for the playability of the FL, along with an easy
upper register but you want a more velvety sound, the FL*** Models are what you
seek.
These models may not play quite as accurately as the standard FL Models
but you will be able to color your sound and attacks more easily.
Want big?
This is it!!

FD Models
The FD Flugelhorn Mouthpiece design is a unique
new concept to improve the match for certain makes of flugelhorns. The FD design
has a shorter overall length, a larger throat bore, more open throat entrance,
unique new backbore, and new shank design.
Used with a matching Flugelhorn the FD provides
a beautiful sound, accuracy of articulation, exceptional intonation, as well as,
even slotting throughout the range of the instrument. FD improves
the match when using a more resistant flugel. The FD is an ideal match for
Conn Vintage One flugelhorns.
This shank may not engage into
some flugels as far as the FL Mouthpieces.
As an added design bonus, the FD
Models work extremely well in most trumpets! The sound is quite unique, almost
like an "angry flugelhorn". This is an ideal set up for post horn solos,
jazz gigs, or when travelling and you simply can not take the extra horn with
you.
