Diezel Einstein - Channel volume v Master

How are you guys running these? I generally just have the channel volumes around noon but I noticed some guys saying they sound best around 2:00. Put them up there thought I was getting more lows? Maybe my imagination?

they act as fx send vols - so it depends if you have something in your loop or not.

at low playing vols it is a nice variation to crank the master and use the channel vols as "vols" then.
