Hello Jodi, thank you for answering my problem, it's an Italian system accordion. However, what bothers me is the (2) fastenings of the straps that are made on the C, back side of the instrument. and not above and below as it is usually done so it is impossible to wear and play. I bought it without the straps. it also has a 6mm jack plug on the bass side with 2 microphones inside which works well.the button of the bellows is at the top left almost at the top difficult to access; when the wheel of tension of the left hand strap it is at the bottom of the accordion.when I say weird the accordion ..... thank you again. friendlyemnet. bernard zanit perpignan ;
