"The band uses many homemade devices as instruments, such as the Viking Rowboat. Dan Rathbun uses a custom-stringed bass instrument referred to as the Sledgehammer Dulcimer (or, alternately, the Slide Piano Log), which uses piano strings and is possibly more than 7 feet long; it is played with two sticks: one in the left hand generally used as a fret, and another in the right hand to strike the strings.
Percussionist Michael Mellender's instruments consist of restaurant kitchen equipment, trash can lids, and other "found" metal objects, in addition to traditional percussion instruments. One of the more infamous instruments used by the band was Moe! Staiano's Popping Turtle."
