Re: Angus Young
Angus only used that stuff for the Razor's Edge tour. However, he only used Mesa poweramps, the preamps are Marshalls.
As for Zakk Wylde, he did use Metaltronix amps for his first CD with Ozzy, No Rest For the Wicked. Everything since that though, he's used Marshall JCM 800 2203 amps with 6550 tubes.
