Yamaha C40
The C40 is a guitar that Yamaha describes as "an affordable full-sized classical guitar" and the company website states that it was made especially for all-around guitarists. 

It is rumored that the C-Series guitars of Yamaha have been around for as long as 1986, where it conveniently marked the unprecedented emergence of the first hundred of these C-Series C40s. Little is known about these first hundred (prototype) units that were produced during 1986, but the fact is that the C-Series C40 was yet to be publicized at the Hamamatsu Yamaha factory until 1991.

Until this day Yamaha still makes new versions and improvements for the new C40 models.
