yes, it's played like a 12 string guitar, or and 8 string bass.
they are played by hitting 3 (2 in an 8 strings case) at the same time, giving it a fuller sound. the tunings for one would be Eee-Aaa-Ddd-Ggg. for each standard bass string there are 2 smaller (long guitar) strings that are one octave higher.
sTEVE!
