Do you repair other makes of clarinet?

  •  Due to the high demand for our team we can only repair Kronthaler clarinets unfortunately.

 What is a "Klarinettencheck"?

  • Klarinettencheck is a quick regulation appointment without oil bath, before an important concert or if the instrument has not been overhauled in a while.  The duration of the Klarinettencheck can be between a couple of hours and a maximum of three days.

What is a part-overhaul?

  • Removal of the keywork, necessary mechanical repairs, one week oil bath, basic cleaning of the body and key work, replacing of all damaged cork, pads or springs and the regulation of springs. The key work is then re-assembled and the clarinet regulated. Customers may choose between a small and large part-overhaul. The price depends on the time worked and costs of raw material. The duration is approximately two weeks.

 What is a general overhaul?

  • Removal of the keywork, necessary mechanical repairs, one week oil bath minimum,  thorough cleaning of the body and keywork, replacing of all cork, pads and damaged springs and regulation of all springs. The bore of the barrels are re-measured and, if necessary, adjusted to their original measurements. The keywork is then re-assembled and the clarinet regulated. The duration is at least three weeks.

Can I have an overhaul any time?

  • Yes, if you book in advance. Our busy period tends to be between July and September, when we only overhaul clarinets for our customers who only own one set of clarinets and/or require an overhaul during the orchestra summer break.
  • Please book your overhaul appointment at least 3 months in advance, except appointments for the summer period, which should be placed in March. To avoid any misunderstanding, all bookings must be done by email (

 When do you accept reservations for summer overhauls?

  • From March every year, we start to take the overhaul bookings for the coming summer. We can only take overhaul bookings if the exact dates required are stipulated (e.g. the dates on which the clarinets can be in the workshop “from ??- until ??”).

 Are there particular things I should be aware of when sending the clarinets?

  • Please print and fill in our repair form and send it together with your clarinets. All reeds, music sheets etc. should be removed from the case before. Only the barrels, clarinets and mouthpiece you use should be in the case. If you have a favourite barrel, please mark it clearly, so that we are aware of your preferred intonation.
  • Your clarinets should be in their case and the case should be sent in a large, well-padded (and if possible well insulated) cardboard box.
  • For customers living in Germany, we recommend that you ship your clarinets with DHL, as they offer an express service with a relatively cheap transport insurance.
  • Customers from abroad should consider taking out a transport insurance if their regular insurance does not cover transport.
  • We do not accept any liability for instuments in transit.
