The models 5 and 10 and 20 have been discontinued by Bernabe. These were production guitars made to his specs by one of factories in Valencia. Bernabe broke off his relations with this factory as the result of a personal dispute, which had nothing to do with business or their guitars. He looked for another supplier in Valencia, and tried another shop, but the shop was unable to meet his high standards, and its owner unwilling to make the changes that would be necessary. As a result, he moved production to his shop in Madrid where he has four luthier and a couple of assistants working under his direct supervision (on the model of the old Ramirez shop when his father was its forman). This shop is now making the models 15, 30, 50, the 640, and his flamenco model. These are all handmade guitar built with traditional methods. The model 15 is a concert classical guitar, not a student model. As he explained to me, "it takes the same amount of time for us to build a concert guitar as it does an estudio model, so I decided we can't afford to build estudio guitars." The primary difference between models is in the quality of the woods, and appointments. As one goes up his line, the woods become of an increasingly higher grades, and when it comes to his own production-- the PB line--which he makes in his workshop in his home--the woods not only become rarer and finer, but also from his personal stock of aged woods (tops that may be 40 to 100 years old), and for his best work of a quality is only found in heirloom woods passed down within families or obtained from luthier's who have retired or from their families when they have passed on.
Anyway, while their are appreciable differences between his models-- mostly these are heard as greater clarity, and richness of tone, greater responsiveness. What I find fascinating is that Bernabe guitars have a recognizable sound regardless of the model, or who did the building-- which is a matter of the families experience and careful experimentations. In this regard, Paulino is always thinking. At the recent NAMM, show we spent an hour talking about how the guitar's nut might be improved.
I recommend the Model 15 without reservation. It is a guitar that works records well, and has the power to fill any concert hall.
