Thanks for your comments about the vocals.
For the bass I can't take credit. The bass goes through an amp cabinet plugin which makes the bass real low. I eq it at 70, 170 and a narrow band up around 9k, but the amp model really makes the bass.
The master bus has Vintage Warmer - so some squish and raise about 170hz/5-6khz, not much though. Then there's an eq with gains in bands low and high but not really middle. The eq also has some 'vintage' color in it.
There's heaps of eq'ing on a track to track basis. Each drum has maybe two or three passes.
I am sure that going from 16 bit to 24 bit has helped a lot. I always used to get mud in the low frequencies. So far with 24 bit I'm like Helen Keller suddenly hearing faint sounds like birds in the trees and stuff. There is so much more clarity.
I think that helps for loudness because having every sound distinct you can boost each one. If it is muddy each is not distinct, so the eq is important for loudness.
LightningMp3 keeps your song in the original way you mixed it down, in this case 24 bit 320 kbps. So, it's not squashed and made muddy.
Just IMHO.
