thank you for your agreement!
i've found this strange kind of guitar in a village-fair in my country (near milano). it's a sardinian guitar an instrument of the middle of the 20 sec i think...
in this photograph you can see the great american guitarist stefan grossmann with one of this guitars.

it sounds like a american martin guitar but is tuned a third or a fourth under the normal guitar.
i find it very interesting on playing early-baroque music...
have a good 2014!
greetings from italy!
