I have a Kasuga G300 classic guitar , brought new 1976. There were a few around at the time sold in music shops and thru my music teacher k Clancy. They were 190 bucks at the time, played fantastic. I have played it most days since then, the neck is straight, as they were steel reinforced, Rosewood body and Fret board.   It still plays great , no bending of the neck and just stays in tune. Theye were rated some of the best sounding Acoustic guitras of the day and will be a classic still in 100 years. Nothing wrong on buying quality don'nt sell them.
