"His main instrument since the 1970s, Waters uses this P-bass for all of his bass parts on the show. It's the model his signature model is based on. He uses Rotosound 66 strings. Waters keeps a clone of this guitar made by the Fender Custom Shop as a backup and he also has a clone with a rosewood neck that's used only for the front of the stage, where the instruments are supposed to be dark."
Zach loves his Sovtek Mig 60 head, which he plays through a cab he built himself at a pipe-organ shop in Denver. Every glue joint is lined with thin leather for maximum air tightness, and it’s stocked with Celestion G12M Greenback speakers.
