Guerrini accordion with accompanying case. The first owner selected this accordion personally at the factory and chose it, amongst others, for its gorgeous sound. The second owner is now selling this accordion as he/she is retiring. The accordion has tight tuning and is therefore suitable for classical and non-Western folk music. 2 x 8 feet. Cassotto (sound boxes). 16 feet is cassotto. 1 x 8 feet is cassotto. The synthetic casing for the connection to a sound installation via a jack plug is somewhat damaged. As far as I know, this hasn’t hampered its functioning. This function has never been tested though by the current owner. See photo.
