OK, this is what I hear,
#12 is the tape. At least I hope it's the tape because I don't see how dumping to a digital format could bring space back around the drum kit. This file seems to have the right amount of bottom,in that, when the drummer hits the floor tom, I can tell it's a lower pitch. I can barely make that out in the other two files. I can hear the image of the kit better also.
#11. It sounds strange up top to me{like a filter} and the drums don't sing as good. Also, when the band lands on the b flat and the guitars go nut's, it sound's like something sags,or it empties out . It's like there's a compressor on the bass and I can hear it working. Or, audio amps can't keep up.. I don't know.
#10. It sounds a whole lot like 11 except, it sags worse after the change. The EQ filter thingy is present again. I think this whole sag thing is a "change" in tha bass guitar I'm hearing. For instance, the snare sounds the same on both digital files to me.
The biggest difference I hear is in how they image. The kit sounds right to me on 12 and the other two files sound like they collapse a bit and cheap high shelving EQ was used or something..
There is a guitar in the intro moving from a c to an e flat a few times before the change. This is down in the mid end and is slightly harder to hear on #12. to me.
Well, that's my 2 cents. and I'll have to live with it. I could be wrong, that's for damn sure. FWIW, they sound less different than I thought they might.
I wish something with real long low end was used. And I wish the low end was clean too. There ain't much bottom on the music to begin with.
EDIT: I thought I might ad that, I would not call the differences, Lopped off bottom end and in fact, the perceived lack of bottom,{small as it is,} could be a slight raise in the mid band os something. .
It could be that something was wrong with the rig when this happens to people?? I don't know. But,no drastic drop in bottom. Period.
