This great playing and sounding Busato has a story. It started its life as a 12 frets Busato, and was later modified as a 14 frets by the great french luthier Alain Mazaud. It was also refretted by Béranger Griot.
Three of the most experienced luthiers specializing in Busatos declared it is a Busato. It has a Busato label. There is a blog in Germany which believed it is a fake. I think these guys are fake Busato experts but surely not fake idiots.
Here are two videos of this guitar. Do you like the sound?
