This is a thin-body acoustic guitar from Grassroots. It seems that Martin dreadnought types and Gibson J-45 types were sold at the time, but I am selling the former. Grassroots' G-AC-45 is famous for this type of guitar, but this one is a dreadnought shape. It has a 610mm short scale and is small overall. It's a very interesting concept guitar, and I finally got my hands on it after a lot of searching, but I'm selling it because I need the money. There is no solid body type, and it is a proper acoustic guitar, so it produces a decent acoustic sound. I think it's perfect for switching from an electric guitar or for grabbing it quickly in your room. It's not too small like a mini-acoustic guitar, and it's also perfect for small women and children. It has a through-type bridge, making string changes easy. Above all, the dreadnought body is cute! The last photo is a size comparison with my full-size dreadnought. Please understand that I may withdraw this listing if my other guitars sell. Mini guitar
