Video review! This brand new GS15 offers maximum bell resonance in a lightweight, high efficiency design. The only one ever made. The GS15 trumpet was built to test new prototype bracing laser sintered from 316L Stainless Steel. Jason has just finished a full spectrum analysis of this instrument to further develop upcoming high efficiency trumpet designs.

GS15 Stainless steel prototype
This brand new GS15 offers maximum bell resonance in a lightweight, high efficiency design that is COMPLETELY adjustable in terms of impedance, flexibility, slotting, and air flow. The only one ever made.
This is your opportunity to own a true piece of trumpet innovation history. This is the first, and only, trumpet testing both brass and stainless steel H-series top bracing. The goal with this prototype was to increase bell resonance and efficiency while reducing weight. Spectrum analysis and further testing has shown this experiment to be a success. Bell resonance has increased significantly thanks to this new bracing design. Watch the video below to hear this amazing one-of-a-kind prototype trumpet.
- Leadpipe H1 - drawn design similar to our SWE #1 leadpipe
- Bell 3R - red brass large taper, warmer and more responsive, tone color adjustable w/VGR & SpectraTone Mouthpiece
