I never really listen to TOOL that much but in the past year I started to listen more. The show at the bill graham was insane on Thursday. The music along with Alex Grey visuals really take the music to a whole other level. I now see why so many people are obsessed with Justin chancellors tone! haha. They opened up with Led Zeppelin's No quarter and that was it for me after that (I never got heavy into zeppelin but, no quarter is one of my favorite songs from them!). what frequencies do you guys think he's cutting and boosting especially mids? I switch between using a mesa boogie bigblock 750 and walkabout. I know this has definitely been discussed before but I am not at all trying to achieve exact tone as I know there is so many variables to that. just interested in how he gets that hit you in your gut sound. it was the first show I've been to where my insides were rumbling and I HAD to use ear plugs! haha EPIC.
