Hi Herb.
A few things, here to be cleared up.
The vox are "too perfect" to be double tracked
They are all tracked up - six tracks each for me and Jess. It just takes practice.
I hear comb filtering in places which leads me to believe you did clone the vox
With twelve vox tracks running, using the same voices and panned hard left/right, you're always going to get some "comb sound" whether you clone or track-up. If the tracks were all cloned, as you suggest, then the phasing effect would be exactly the same throughout, not just in places as it is. Basically, the multi-voice effect is what we wanted for this song.
Things are pretty heavy on the fx
No effects other than compression on the vox tracks. A little stereo delay on the lead guitars. Tracked-up stereo on the rhythm guitar. Chorus on the piano.
Thanks for listening.
ROG.
