Metallica is the biggest band on the planet. I’m not saying that as on opinion, at this point it’s just a fact. No band is bigger than Metallica. And being the biggest band in the world is a lot of work believe it or not! They have a MASSIVE crew that takes care of everything that isn’t the music part of a Metallica show, which is probably 95% of a Metallica show. Two of those crew members are guitar gurus Chad Zaemisch and Justin Crew (convenient!), and in this video from Guitar World, they walk through everything that needs to happen for those guitars to make noise.
These fellas really know their stuff! They walk you right through the signal flow of both rigs, the guitars that are using, and potential problems that could happen.
You know, there’s not too much here I could tell you that the boys couldn’t tell you themselves, so I’m just going to let them take it from here. If you want news on what the band is up to, go to their Facebook I guess. Or you could look literally anywhere else for Metallica news.
