“If I need something special to be done on my horn, I go to Servette-Music. They are my reference in terms of gear availability and expertise!”David Rey (solo trombone player at the Brussels Philharmonic Orchestra) says about Servette-Music

“The Hagmann rotary valves are homogeneous in all registers and mechanically perform very well. The intonation is great; the sound is full and well defined, thus allowinggreater expression from pianissimo to fortissimo. The resistance between straight Bb and F registers is similar, which is fantastic. My customized Hagmann horn is the best instrument I have ever owned”Francesco d'Urso (Moya trombones) about his custom tenor trombone sporting a Servette-Music/Hagmann rotary valve
