Here ya go, the LOTB setup:
Stage right guitar tech Sean Brady looks after Adrian Smith, having been his tech for the last 16+ years. “Over that time, as the type of equipment evolved, we have found different ways to make it easier for Adrian to do what he needs to during the show. The basis for his sound has always been Marshall amplification and cabinets, using Celestion speakers, with a Shure wireless system. At the moment, we’re using Marshall JVM 410H heads, as they are very versatile with four channels and three voices per channel. They are also MIDI controllable, which gives Adrian a lot of options during the show.”
RF for guitar has also evolved, Brady notes. “We’ve just brought in the new Shure Axient wireless system on this leg of the tour and are very happy with the sound and its ease of use. We use the Dunlop remote rack Wah unit to allow Adrian to have a remote Wah pedal out on stage without having to send the signal down 120 feet of cable but still having that great Dunlop Wah sound! For the last eight years or so we have been using a Voodoo Lab GCX audio switcher and Ground Control Pro MIDI pedalboard. This lets Adrian control various stomp boxes in his rack, his JVM heads and his Lexicon FX unit, using the pedalboard out on stage and allows me to do the same from a second board I have by his rack. The GCX gives a good transparent audio signal and gives us a versatile option for the different stomp boxes and FX loops he needs. At the moment, he’s using a Boss CH1 Super Chorus, Boss CS3 compressor/sustainer, Ibanez Tube Screamers and a DigiTech Eric Clapton ‘Crossroads’ pedal. His main FX unit for different delays is the Lexicon MX300. We have used Lexicon for the last 10 years and it gives him a lot of flexibility with his delay sounds and the control of them through his MIDI pedalboard.”
Peavey preamp is gone and also JVM's seem to have been brought in because of the MIDI switching.
Basically the current H's setup is:
Guitar -> CryBaby Rackmount -> Tube Screamer 1 -> Tube Screamer 2 -> Digitech Crossroads -> CS3 -> CH1 -> JVM Front -> JVM Send -> Lexicon MX300 -> JVM Return
All in loops of the VoodooLab GCX.
*It's possible that CS3 and CH1 are in the JVM loop too.
Controlled by VoodooLab GCX.
The rack-mounted Marshalls are spares and were used by Dave in 2017, when his JMP's were getting rebuilt AFAIK.
