Saludos,here is the CVS Bongó,made of 3/4" thick Red Cedar,not heavy at all(10 pounds). It is beautiful made & beautiful sounding piece with mule skin on Macho & thick Cow skin on Hembra.Outside measures are 7.25" X 8.25" but as it is made cylindrical shape the Hembra botton opening is bigger (6 7/8") than in my Matador and bigger (5 3/4") than the Matador Macho. Also has the same size openings as on my Moperc. I paid $350 and could be up for sale so if anybody is interested let me know. The CVS is made by a Bongocero so the sound is like is suppose to be ,OLD SChOOL. Will be taking him to rehearse tomorrow and to gig next saturday the 29 as I be playing with Conjunto Akangana .
