KORG RHYTHM KR-33 Analog Drum Machine

via this auction
"rare analog drum machine from the late 70s or early 80s... this is one of the not-so-frequently-seen KORG KR-33 "RHYTHM 33", made in Japan of course. it's the older but bit smaller brother of the KR-55, which we see for sale more often than the 33's. it's almost the same thing, actually, but these are light gray in color, 16 rhythm-select buttons and the 3 colored buttons to select the rhythms from either the orange, black or green "selection". so it's basically 16x3= 48 sounds/rhythms available. but you can also push 2 of the gray buttons at the same time... AN UNIVERSE OF POSSIBILITIES!!! oh yeah!"
