John, I presume you are asking about the Sho-Bud. Your link gives a listing of mandolins, a banjo and the Sho-Bud. It is a pedal steel guitar and is played by sitting at it and plucking the strings while sliding a steell up and down the strings. The pedals change pitch on the strings as you do this.

A well played pedal steel is an incredible sounding instruent. Listen to Roger Gilmour of Pink Floyd.
