Certainly no other name in flamenco guitars is quite as well known as Conde, and the reason is actually pretty simple – no other guitars are played by as many of the top flamenco players in Spain.
Paco de Lucia has played a Conde since the beginning of his career (and many players from the generation before Paco played them as well), and while Paco has surely had a huge influence on almost every flamenco guitarist since, it’s hard to imagine that he’s the only reason so many great players play Condes.
