This is one of the best Russian button accordion (bayan) Agate Double Cassotto with a Converter Bass system.

This bayan meets all the requirements for professional musical instruments. Bayan Agate is known by musicians of all kinds, both beginners and professional players. This button accordion can satisfy the most demanding musicians with the best taste.

You will be pleasantly surprised by the beauty and superpower of its sound! This button accordion (bayan) will be good for any advanced professional users for concerts and shows of any kind.

This bayan has a converter bass system. It has a switch on the bass side, allowing it to play as a free bass or a stradella! A free-bass system is a system of bass buttons on an accordion, arranged to give the performer greater access to playing melodies on the left-hand manual of the instrument and to forming one's own chords by providing a button board of single-note buttons with a range of three octaves or more, in contrast to the standard stradella bass system which only allows bass notes (range of a major seventh) and preset major, minor, dominant seventh, and diminished chords.

The bayan comes with brand-new leather straps and an original case.

Pay attention

Almost every used accordion private sellers/owners offer requires small or considerable maintenance. High-quality repairs and tuning of the accordion are expensive: sometimes, the charge for repairs exceeds the cost of the instrument itself. That is why we recommend you buy instruments from licensed sellers with big experience and profound knowledge in this area, such as our musical workshop. Our musical workshop, “Harmony,” sells not just used accordions but also ones that are thoroughly checked, restored, tuned, and 100% ready for playing. The qualified masters of our shop carry out this work.


We guarantee that if you buy this accordion, you will get it fully working to play it right away. Otherwise, we will refund you your money. You can return it within 14 days of receiving it.
