C-670, Yulong Guo (China)


Slightly used in very good condition

640mm short scale concert double top model with Koa back & sides & traditional fan bracing !!!

The Concert model uses the latest classical guitar technology invented by German luthier Matthias Dammann in the late 1980’s 

A double-top with two ultra-thin layers of first-class cedar with a sandwiched  layer of Nomex to give all the strength needed for the durability of the top. This technique also reduces the soundboard’s weight, and therefore enhances the guitar’s sound volume and responsiveness by far.

A beautiful guitar, with excellent volume, and singing voice, the quality of its workmanship can be  compared favorably with many other world-class concert instruments…

A must try !!!
