The controversial and ambiguous travel guitar of Sergei Tynka. http://www.travelguitar.ru/ 

All objects are grouped into one group, on 4-6 strings the disconnected but tuned VrayDisplacement modifier hangs. When you turn on displacement, you need to disable the bump in the material. Also, almost all objects have a smoothing modifier for rendering.

The model exported to .obj without antialiasing, the vyr-material for it is in the archive.
