Restoration

Accordions are built to last. Their sturdy construction is designed to make them reliable companions for decades of playing. But even the finest accordion will begin to show signs of wear and tear after years of use. Reeds may go out of tune, keys can start to stick or the bellows could develop a crack. And if an old instrument has been in storage for a while, it might have gathered dust and require a thorough cleaning.

But don’t give up on your old accordion. The Hohner Service team in Trossingen specializes in restoring vintage Hohner instruments and stocks a wide range of original parts. We will be happy to recondition your beloved accordion and restore it to its former glory.

Since 1930, every accordion which left our factory bears a serial number and we maintain an extensive library, documenting shipping date and destination of every single instrument. Sometimes we can even establish the identity of the original purchaser.

If you own a vintage Hohner accordion, or are interested in buying or selling one, you’ll no doubt be interested in establishing its precise age and provenance.

Since 1857, HOHNER produces musical instruments like harmonicas, accordions, melodicas, recorders, guitars and ukuleles of the highest quality.

The founder of the Hohner company is Matthias Hohner (1833 – 1902).

The German Harmonica and Accordion Museum in Trossingen, which houses the famous HOHNER collection, is simply unique and tells the HOHNER history like no one else. More than twenty five thousand different harmonicas and accordions, lovingly preserved by curator Martin Häffner, make up the largest single collection in the world. But the museum doesn‘t only exhibit musical instruments, it also shows rare films, recordings, sales displays, advertising posters, and much more. The exciting story of Matthias HOHNER, his rise to fortune and the assimilation of his numerous competitors is all documented in the main museum building. Special exhibitions are shown on the new premises a short distance away in Bau V, a huge former factory building on the original HOHNER factory site.
