That guitar in the video looks like a '70s Fender Strat with maple neck with the big headstock, a 2 tone sunburst finish, ash body(for '70s era Fenders, I might be wrong),Floyd Rose tremolo bridge, and a Dimarzio HS-3 stacked single coil pickup in the neck position and Seymour Duncan JB pickup in the bridge position. Other guitars that he used onstage were his custom ESP Strat style guitars with Floyd Rose bridge, Dimarzio HS-3 (neck) /Seymour Duncan (bridge) pickups. Steinberger guitar (not sure of the model number) with EMG pickups.
His early gear was a Roland JC-120H amp head for clean, 2 Marshall Superlead amp heads/Ibanez Tube Screamer pedal for his crunch & lead. Celestion G12H speakers in his Marshall cabs. He switched to a guitar rack and used an ADA MP-1 preamp/Digitech 256XL effects processor/Carvin FET power amp.
