Did you know Roger Waters used an EHX Bassballs on The Wall tour? This is a close-up of his Pete Cornish pedalboard—note the switch labeled “Balls” plus this clip from Premier Guitar’s Rig Rundown.

The Electro-Harmonix Bassballs is a classic effect with twin-tuned filters that create a unique vocal tone. It excels on both bass and guitar and is now available in a rugged die-cast package.

Tickets are now on sale for Roger Waters The Wall which is coming to cinemas on Tuesday September 29, 2015. The film has been described as including “concert footage from Waters’ three-year solo tour in which he played The Wall in its entirety as well as behind the scenes footage from France and Italy, of Waters visiting the World War 1 cemetery where his grandfather is buried, the beachhead where his father died during a World War II battle and more.”
