Mike Fraser about AC/DC "Black Ice" recording:
"With AC/DC I simply put one rhythm guitar in each speaker. Often when I mix other people's stuff, the guitars will be in stereo, and then they'll have double-tracked them. In such a case it becomes a depth and a layer issue, which in the track doesn't actually sound that big. The thing about AC/DC is that they don't double-track their guitars. I keep saying to young bands: if you want a really big guitar sound, just get a really good mono guitar sound! Of course, when you double something, it sounds bigger, but in the end result you have less guitar: you have to turn it down because it takes up too much space in the stereo image. The other way to get a big guitar sound is to pan it. Your kick and your snare and your bass will be in the middle, and your background vocals will be a little to the left and the right, and if you pan your guitars further out you get this whole wide spectrum of everything that's happening. In such a situation it's really easy to mix so that everything can be heard and everything sounds loud, instead of everything being on top of each other with lots of layers."
Guitars & bass: SSL EQ, EMT 140, tape delay
"The rhythm guitars are absolutely bone dry. On the intros of some of the songs I added some EMT 140 plate reverb on the guitar if it was Angus by himself. His solo guitar would have had a Studer tape slap delay on it, about 140ms, the same as I used on Brian's vocal. Reverbs are usually too washy for my taste, but sometimes bone dry doesn't give you the emotion you want. In that case a delay can work. There are no effects on the bass guitar."
