Stomvi decided to develop a professional trombone which marked a turning point in the trombone world, and they indeed succeeded. Vicente Honorato took the lead in this project, surrounding himself with those who had devoted their lives to music, and especially to the trombone, and who could serve him as a guide. The Research and Development Department started by following the technical specifications that Vicente Honorato was gradually deciphering. Though unusual in this circumstances, he managed to launch several models onto the market which delighted a vast majority of students, teachers and soloists of bands and orchestras, both nationally and internationally.
