Hi Gazzastapo, I've got 3 charangos, well one actually is a ronroco which is a bit larger charango.
The first one I got was purchased here in Brisbane from some Latin Americans for a birthday
by the wife, its medium size all wood, the 2nd is a small one which I bought in Ecuador, its got
the armadillo shell sound box
and the 3rd is the ronroco a beautiful hand made instrument I bought in Bolivia from a proper
music/instrument shop, its the one I play.
ciao bob
