  • Osmun Music Repair Services

    • Drop Off/Send In
      Drop off or send in an instrument for service. A tech will examine your horn and consult with you about indicated repairs or services. Most repairs take less than two weeks. Let us know when you need your horn, we'll work with your schedule. 

      If you need your repair on a same-day schedule you can book an appointment here. (Some major repairs may take more than one day to complete.)
    • General Repairs
      Dents, broken solder joints, balky valves, etc. When you arrive we'll evaluate your instrument. Minor repairs can usually be done the same day. If we can't repair it while you're here we'll schedule a pick up time or arrange to ship your instrument back to you.

  • Trumpet Services

    • Trumpet Chem\Ultrasonic Cleaning
      Your instrument is completely disassembled and thoroughly cleaned.  We remove old oil and grease as well as calcium carbonate and copper carbonate deposits using a combination of chemical and ultrasonic processes. Your instrument is then reassembled, re-lubricated, slides are aligned for smooth action, and play tested. All corks and pads are replaced. Springs are inspected and replaced if necessary. Regular chemical cleaning greatly retards the process of de-zincification ("red rot") and can double the life of your instrument.
    • Vent Valve-Trumpet
      When you re-position a slide without depressing the valve the pressure differential creates a puff of air that can disrupt your embouchure. Drilling a small hole in the piston allows the pressure in the slide to equalize. 

  • Horn Services

    • Horn Chem/Ultrasonic Cleaning
      Your instrument is completely disassembled and thoroughly cleaned.  We remove old oil and grease as well as calcium carbonate and copper carbonate deposits using a combination of chemical and/or ultrasonic processes. Your instrument is then reassembled, lubricated, tuning slide legs are adjusted for smooth action, strung, and play tested. Springs are inspected and replaced if necessary. Regular chemical cleanings greatly retards the process of de-zincification ("red rot" or pink spots) and can double the life of the instrument. (Note to owners of Engelbert Schmid horns: We have many years of experience cleaning instruments and have done tests on our processes to make sure they are safe for instruments, players, and repair technicians. We don't use any chemicals that attack the metal of your instrument. Mr. Schmid has very specific ideas about how his horns should be maintained. If you wish, we are happy to maintain your instrument using his procedures and recommendations.)

Slides are adjusted for tightness and optimal action.

    • Trombone Valve Cleaning
      Your valve/bell section is completely disassembled and thoroughly cleaned. We remove old oil and grease as well as calcium carbonate and copper carbonate deposits using a combination of chemical and/or ultrasonic processes. Your bell section is then reassembled, lubricated, tuning slide legs are adjusted for smooth action, strung (if string action), and play tested. Springs are inspected and replaced if necessary. Regular chemical cleanings greatly retards the process of de-zincification ("red rot" or pink spots) and can double the life of the instrument. 
    • Open Rotor Port
      The ports in the rotors of many trombones are undersized. This causes a restriction in the air flow that can cause the F attachment to feel stuffy and unresponsive. Opening up the ports in the rotor to full size can make a dramatic improvement in the playing qualities of your horn.
    • Mini-bal Links-Trombone
      Modern Mini-Bal links are silent, fast, require no adjustment and almost no maintenance. Older mechanical linkage trombones as well as newer instruments with inferior linkage parts can benefit from our German-made precision linkages.
