All the woods employed in building this guitar have been aged at least 30 years. The German spruce used for the top is outstanding, and Indian rosewood is superb. Felix Manzanero is one of the handful of outstanding luthiers to come out of the Ramirez workshop in the 1960s (such as Bernabe, Contreras, and Mario Tezanos), and is widely considered among finest flamenco guitar makers in Spain. This handmade concert flamenca negra guitar not only is an absolute gems of the luthier's art, but has the power and tone one expects in a great flamenca negra: profound basses, rich incisive trebles, and an aggressive flamenco bark. I picked this one out myself in Madrid on my most recent visit to Spain.
