The gear Adrian Smith, Dave Murray, and Janick Gers are using onstage
"Murray uses his TC Electronic G-Force (which is sandwiched between two pairs of Marshall JMP-1s and JFX-1s) for about seven patch changes. The G-Force connects to the Marshall JMP-1 effects loop. The JMP-1 then feeds the return of three Marshall JCM2000 heads, which are only used as power amps. All rack devices are connected to a Pete Cornish power supply and routing unit, both of which are visible here above the yellow-taped Korg DTR-1 tuner."
