Joe Perry's Rack
Perry's rack has four Shure ULDX wireless units that are running all the time to facilitate guitar changes. Foster calls the units the closest thing to a cable he's ever heard. The signal from the amps splits to the RJM Effects Gizmo on one side and the Digidesign Eleven Rack on the other, which is set to a Vox tone and just used for monitoring the sound pre-effects. Foster has a Bradshaw switching system above the rack as well, and watches Perry to see when he needs to control his effects throughout the night.
