Dvina is still in development.
Dvina is a wooden electro-acoustic instruments and due to our little experience in production of such devices, it is hard for us to establish the price at the moment, though we expect the net price for the main part (Dvina + the step-up transformer) in the span of 200-500 Euros. The net price for the pre-amp/delay/distortion unit is around 300 Euros.
If enough people are interested in buying the Dvina we can start production. If you are interested please drop an email to omhohom [at] gmail.com
If we will decide to start the production we will calculate the exact price and inform those who expressed interest to buy Dvina.
