The Alhambra 4-Z was already an exceptional guitar when, to commemorate the 50th anniversary of Alhambra Guitars, it was remodeled to create a truly unique instrument. The most important feature of this guitar is the singularly beautiful wood: the back and sides are made from Ziricote (Cordia dodecandra).

This wood produces a deep and warm sound that could be described as reminiscent of Spain itself. Although each guitar is always one of a kind, this is especially true in this model; it is much easier to notice the difference between one Iberia Ziricote and another. It has been designed with a narrow neck which is made from mahogany.
