Back to the Shack

Weezer’s rig tour specifically identifies the Balls Effects Black Balls as the fuzzier pedal used primarily for “Back to the Shack,” chosen because the song needed a creamier sound. The exact studio amplifier and pedal controls are not published, so the Marshall-style platform and settings below are representative while the pedal choice is documented.
