The S3 was designed to offer an extremely easy to play, in tune and affordable instrument. We started with our very successful Stomvi USA trumpet and fine-tuned the air column. We designed a new leadpipe and improved the response through upgraded hardware. Then we added a BellFlex S3 Bell which has produced a truly amazing instrument with a wonderful sound full of harmonics, great slotting, and an easy upper register. The increased resonance of our Bellflex alloy makes the S3 extremely easy to play with advanced slots and a sound full of colors. All S3 trumpets are assembled one at a time by expert craftsmen to assure the highest quality and consistency.
