i've had to stop and start mixing all day to rest my ears. this is not something you want to listen to on repeat at high volumes unless you're using earplugs, but i want to make sure i'm not getting the sound of being dulled to the room reverb on the guitar amps. the effect is in the sudden onset, so listening to it over and over again as one normally would when mixing is simply the wrong approach - i'm going to get used to the roar as it cycles, and end up with the wrong output. so, i have to listen to it loud, stop, adjust, wait and repeat. it's just about there. i think the next run through could legitimately be the last one...

well, for the first 7 minutes, anyways. but that's the hard part. the last 18 minutes is going to be minor tweaks.
