Gold Tone also makes a banjo bass! Tried one. Sucks swamp water.

Somebody a ways back mentioned a Gibson mando bass. Someone brought one to a folk club a few years back. Giant ungainly beast. Player stood at the back of the stage, put on an archery glove (!?) and proceeded to (unplugged) overwhelm the singer/guitarist who had the benefit of playing through a mic! Utterly glorious!
