I have a "one of a kind" 10 lug Pan Con Queso early 70's, brought over from Caracas Venezuela. New mule on macho, calf on hembra. Incredible sounding pair and very light weight. Nice size, macho 7 1/4, hembra 9". You will never find a set like this. Made by the master Carlos Landaeta (Pan Con Queso). Attached: Photo of the bongos and of Pan Con Queso playing bongos.
