There are multiple instruments referred to as a bass banjo. The first to enter real production was the five-string cello banjo, tuned one octave below a five-string banjo. This was followed by a four-string cello banjo, tuned CGDA in the same range as a cello or mandocello, and modified upright bass versions tuned EADG. More recently, true bass banjos, tuned EADG and played in conventional horizontal fashion have been introduced. There are also varieties of bowed cellos with skin resonators that use this name.
