Chicago Brass Works - Custom Trumpets
Trumpets GS

The GS series are unique trumpets in the Chicago Brass Works™ lineup. Using a     ML 460" / 11.70mm bore in conjunction with our special two piece multi gauge rimless bell design, we've merged a wonderful balance of a medium weight valve casing to add tonal depth while retaining fast response.  We offer our standard Brass Bell Stem and Flare, a first of its kind Copper Stem or Nickel Silver Stem with Brass Bell Flare to provide players various tonal colors and playing response.


Special adjustments are made to voice the trumpet to speak clearly with a secure center and slot. We are the only manufacturer to Cryogenically process each trumpets to increase resonance and reduce any stress in individual components. We are the music industry leader in this field with over ten years of experience.  Further modern technology allows us to inspect each trumpet and individual parts using computer analyzation to hold set standards and keep each instruments within specifications.

The leadpipe uses a tube over tube design that suspends the receiver to bell brace from having direct contact with the leadpipe tube itself.  This in turn limits dampening to a minimum which results in improving  not only response but projection as well.  The bell to leadpipe braces (2) are also acoustically positioned according to each bell and leadpipe resonance characteristics to enhance and maximize each trumpet quick response while being stable at loud dynamics. Using a 395 gram two piece valve section further adds to this model core like timbre, providing strong overtones in the middle and lower harmonics.  This is further balanced by combining the use of standard weight caps and finger buttons along with the most exact Precision Valve Alignment available today. Each valve is aligned to be within .001" in both the up and down position.  Creating a very balance and even playing trumpet with a balanced response center.
