The 11P’s fingerboard is longer: it goes over the sound hole in order to introduce an additional fret that is required for high graded players to play some musical pieces (compositions). There is also and additional green line in the binding and inlays. However, the most important is that the heel on the 11P is made of 5 different pieces while the other models have a single piece heel. The structure on the 11P is much stronger and surely this has an influence as well in terms of sound.
