For years now, U2 guitar legend the Edge has tapped rig-maker to the stars Bob Bradshaw to route and program his über-elaborate switching system. The effects are controlled by two Bradshaw RS40 controllers. One is onstage (center), and the other is offstage being overseen by longtime tech Dallas Schoo. Adjacent to the onstage RS40 are a DigiTech WH-1 Whammy, a Boss 500V expression pedal (which governs a CAE remote wah), two Dunlop Volume (X) pedals (one controlling reverb parameters and one controlling delay settings), and a Dunlop Volume (X) Mini for manipulating pitch shifting.
Edge’s “pedalboard” controls two large rack units containing a variety of rack processors, stompboxes, and auxiliary devices, including a Korg Pitchblack rack tuner, multiple Fractal Audio Systems Axe-Fx II XLs, three Line 6 units—a custom DM4 Pro Rack, a Pod Pro, and an M5 Stompbox Modeler—a Korg SDD-300, an Ibanez TS9 Tube Screamer, six Boss stomps—an FA-1 FET boost, a CS-2 Compression Sustainer, an OC-3 Super Octave, and three SD-1 Super Overdrives—a Fender prototype distortion pedal, a Diamond Pedals VIB1 Vibrato, an Electro-Harmonix B9, a DigiTech Synth Wah, a Voodoo Lab Pedal Power Mondo, four MIDI Solutions Mergers, a JHS Crayon, a Sobbat DB-2 Drive Breaker, and several Bradshaw-designed Custom Audio Electronics splitters, loop boxes, and interfaces. All of it runs through Furman PL-PRO DMC E power conditioners.
