from that interview, talking about malcolm:
Musician.com: What does Malcolm use?
Banks: [...]He uses heavy gauge Gibson strings, .012 to .056.
Musician.com: Any pedals or effects?
Banks: No. He's got the Samson wireless just like Angus. It comes out of the guitar into that. I've got a four-way A/B box because Malcolm pops a lot of strings. He plays with a heavy Fender pick and he basically wears them away. He goes through about 40 or 50 picks a night, and he'll sometimes dig in and pop an A or D string, usually the D. So I've always got three spare guitars wired up and ready to go.
the guy wears 50 picks a night and pops 12s like they're nothing?? that's crazy!
