My Dad played what he called Gypsy guitar when he was in Poland. He lived in Byalstok which is quite near the border with the Ukraine so I am not sure if this was a Polish thing a Ukkrainian thing or a Gypsy thing! Anyhow, The guitar he played was 7 string! The extra one being, in note, in the middle and it was tuned to an open chord but I would have to figure out which. The other guitar he mentions though is the 11 string! The one he talks about was tuned just like the 7 and the extra 4 strings, at the top, were only used 'open' as drones. Dunno if this is what the one here is like of course but it is an interesting co-incidence. To me anyway:-)
