Advisory capacity

We believe advisory capacity is of utmost importance in our trade. Meeting your requirements is a task we want to achieve and therefore will take the time to listen to you at length. If you are a beginner, we will guide your first steps but also follow your musical evolution and advise you in the choice of a higher end instrument. Our selection and stock of instruments have been established accordingly for excellence amongst passionate amateurs as well as accomplished professionals who have found what they sought in our trove. We will take the time and give you our willingness to allow you to try our range of instruments to help you to find the model that will give you entire satisfaction.

Our rationale is based on the selection and implementation of the best available brands available on the market. We have a permanent stock of instruments in all price ranges, from the most affordable (that we select very carefully) to the most prestigious rare birds. Whether it is a woodwind, a brasswind or a guitar, each model is very strictly controlled by our staff, each of whom is a musician, passionate like you !

We have the weakness to esteem the most outstanding instruments. Our selection in the high-end has given us a large customer base of professionals and amateurs who have found their gem in our store. Ultimately, our goal is to provide you with models that truly meet your needs, tailored to your budget and make sure that your choice will fulfill your expectations in the long term.


Our workshops are our second mainspring. Six craftsmen pool their talents in order to ensure maintenance, repair and modifications of your instruments in three different workshops.

• The woodwind instrument workshop: for keyed instruments (flutes, clarinets, saxophones, oboes, bassoons etc.). You will benefit from our staff’s experience and know how, from a simple adjustment on a study instrument to the complete restoration of a professional one. This expertise has assured the loyalty of numerous clients, conservatories, bands, and music schools in both Switzerland and France and in particular that of the Orchestre de la Suisse Romande and international soloists.

• The brass instrument workshop: we have built special tools for dent removal on sax horns of all sizes (from piccolo trumpets to bass tubas). In the expert hands of our craftsmen these specialized tools will erase the traces of the most vigorous use your instrument has been submitted to over the years. We also have the necessary facilities for the elimination of oxide accumulated inside tubing, which ensures the long life of your valuable investment in addition to regular maintenance.

• The stringed instrument workshop: whether it be a routine service or a full re-varnishing, the skilled hands of our luthier will restore perfect tone to your acoustic or electric guitar. His atelier stocks twenty types of fret wire, all re-fretting can be done according to the original manufacturer’s standards or according to your personal wishes. Our services are not only limited to the guitar however: basses, banjos, mandolins, ukuleles, aouds (Middle East traditional luths) and zithers are among other instruments that we regularly handle.


Optimization is our third mainspring. We have designed and registered the trademarks of products highly sought after by professionals throughout the world. This custom production is part of a register of skills that we feel privileged to offer you. Many professionals benefit from those bespoke achievements we have undertaken exclusively for them.

Furthermore, our craftsmen have acquired recognized expertise in ergonomics applied to musical instruments. They may simply contribute to a better guitar neck set-up or string height adjustment, but also improve your velocity and dexterity by customizing a woodwind instrument key work to suit it to your own morphology. Our luthier can also increase the aesthetic beauty of your guitar by adding mother of pearl inlays to accommodate your most creative visions.

Finally yet importantly, we can assist musicians with a distinct morphology, such as very small or injured hands. Our craftsmen have often been approached to solve such problems for their recognized in depth knowledge of ergonomics and skills to extend keys accordingly.

VSB (Swiss association of brass & woodwinds makers and repairers)

Vereinigung Schweizer Blasinstrumentenbauer und Reparateure :

We are privileged to be a member of this prestigious guild whose requirements are of an exacting level. It is a highly exclusive club numbering only twenty-three carefully selected members throughout Switzerland! Our entire team is committed to maintaining and indeed constantly raising the standard of our professional activities to ensure that our profession exalts the highest artisanal standards


Servette Music was founded around 1955 by Otto Hagmann (1914-1980) who was a re-converted engineer who turned his talents to bench made trumpets and trombones. The first workshop in the Charmilles neighbourhood of Geneva specialized in the repair of trumpets for symphonic music and was visited by a number of prominent musicians (including Paolo Longinotti, first principal trumpet player of the Orchestre de la Suisse Romande). Otto Hagmann concentrated on the repair of trumpets for symphonic music, especially in keys which were hard to find on the market at that time, such as D, Eb, F and G. He constructed and repaired many trumpets for customers of brass and marching bands and in addition sold instruments of various brands.

The development and progression of his business led him to move to the neighborhood of Servette in 1970 and the store now is named Servette-Music. One of his three sons; Rene Hagmann; who is also a precision mechanic, joined him in 1971 to specialize in keyed instruments in addition to brass winds. The store’s reputation has steadily grown over the years and its excellent reputation now draws customers from all over Switzerland as well as neighboring countries.

The ever-growing customer base also helps to train employees. In 1979 Servette-Music hired Yves Imer as a specialized commercial partner. His knowledge of both the guitar and sales management led to a decisive change in the company’s subsequent development including the creation of a section of stringed instruments. This was also the year that René took over the ownership from his father who pursued his activities with the team until his tragic death in August 1980.

At the end of 1987, the store expanded and doubled its surface and the “Servette 92 Music” label was born; the new arcade is located at 92, rue de la Servette. The team now numbers approximately thirteen staff members and includes specialists in brass, wind, keyed instruments and the guitar. The specific strength of the entire Servette-Music team is their ability to repair all the instruments sold in the shop which has ensured long-standing loyalty among customers.

In addition to repair works and sales, René Hagmann is passionate about improving certain weaknesses of clarinets and specifically F basset horns. His collaboration with the famous French company Buffet Crampon resulted in the creation of a more evolved and sophisticated instrument which has enjoyed international success.

In 1992, René Hagmann invented a new rotary valve for the trombone; the “René Hagmann Free Flow valve” whose worldwide success led him to establish a new workshop dedicated to its production. This valve which upgrades trombones became very popular with the world’s most prestigious brands and our workshop also specializes in converting and improving existing trombones.

Today Servette-Music distributes a dozen exclusive brands in Switzerland, represents approximately a hundred others and supplies patented products to thirty shops in the world. Servette-Music has received the 2009 Crafts Award granted since 1991 to the most deserving company in recognition of the quality of its work and the commitment it makes to ensure the teaching and transmission of technical know-how.
