These instruments were diatonically tuned with 34 strings, however they did not have sufficient volume and did not allow the player to play in different keys easily.
In 1976 the magazine "Narodna Tvorchist' ta etnohrafia" reported that the Lviv experimental factory was planning to manufacture 2300 instruments a year.
The minister of industry D. Babenko stated that the number of concert banduras with mechanisms manufactured will grow to 1500 in 1980.
Later production of concert bandura stopped completely because the factory was unable to obtain lathes of suitable quality to manufacture the mechanism parts.
This instrument is of smaller size, continuing to have 15 basses, but having only 56 strings rather than 58 with a range up to top G. In the 1990s after the proclamation of Ukrainian independence the economy changed from a Soviet to being market driven one.
Many trained craftsmen left to go to facilities where the pay was more lucrative and the fine skills were not required.
As the economy of Ukraine continued to sink to new lows, efforts were made to separate the bandura workshop from the factory.
After 2000 orders began to be received which stopped the factory form closing the bandura workshop.
Currently there is a 3-year wait for orders, the price of banduras has tripled according to market demand and there is a perceptible change in the quality of the instruments being manufactured.
Currently 4 models are available In 2000 they intend in enlarge their production and including a new Kharkiv bandura with mechanism in its manufacturing plans.
