This is an acoustic guitar bridge and there’s something wrong with this picture. Well, the picture’s ok, but there’s definitely a problem with the guitar. 

You can see how low the saddle is. The string’s have no ‘break’ angle over it—that first string sits almost horizontally on the saddle. 

This means the strings impart very little downward pressure to the saddle. No downward pressure means that much of the strings’ vibration is lost rather than being transferred into the guitar top (which is what provides most of your tone and volume with an acoustic instrument). Poor tone and poor sustain.
