It appears that an edition of Corbetta's Varii Capricii per la Guitarra Spagnuola (1643) edited by Giangiacomo Pinardi, was published by the publishers Guardamagna Editore, in Pavia in 1996.
I have been trying to get hold of this without success. I e-mailed the publishers but they haven't replied. Does anyone on the list have a copy of it or know where I might get hold of one? Best wishes Monica To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
