S.E. Shires Trombone Bell
This is a group of replacement bells for S.E. Shires modular trombones. S.E. Shires bells are made by hand in their Boston factory. They are labeled (underneath the tuning slide receiver facing inside) beginning with a number and a letter, indicating the bead (rolled end of the bell), construction, and alloy.
Bass BII 7GM - bass trombone, large taper, 9.5", gold brass, medium weight
Bass BII 7YLW - bass trombone, large taper, 9.5", yellow brass, lightweight
Tenor 2G - tenor trombone, 8.5", gold brass, unsoldered rim, lightly used, perfect condition
The 7 bells feature a soldered bead: favors pointed articulations and centered sound. Type 7 bells are a modified 2 piece construction, made to combine the best playing characteristics of both one piece and two piece bells.
Other numbers and letters after the first two signify a variety of options and are sometimes combined.
Y = Yellow Brass: 70% Copper, 30% Zinc. Clear, pure sound with strong fundamental, keeps a very consistent tone color and overtone structure throughout the range of dynamics.
G = Gold Brass: 85% Copper, 15% Zinc. Combines many of the characteristics of yellow and red brass for a very balanced and flexible sound.
Markings specific to bass trombone bells
LW = Light Weight: Very resonant and brilliant with quick, easy response.
M = Medium Weight: Slightly lighter than standard.
HW= Heavy Weight: Holds together very well at loud dynamics, can require more effort to play.
T7 = Treatment 7: Thinned in flare, for some players provides easier response than standard.
S.E. Shires bass trombone bells are available in two flare dimensions, indicated before the other markings. If nothing is indicated, it is a BI flare.
BI = compact flare: strong core and easy projection.
BII = wide flare: very broad sound.
