There was some sort of anomaly which made me look up at the time, but for the life of me, I can't remember what it was now, but the tape thingy you mention, just might have been it, or I could be just imagining it now, as it's really close to the end of my day, and I'm soooo ready for bed, but if you find it, let me know.
Wot really confuses me is that Chris Squiers oversaw the whole project, which makes me think, it just might be further along the chain, and all I can think of, it was the 'cutters'.
Due to the fact they were 'Suites' meant they had to fit the record, and wot easier way to do that than to pull 60Hz, which would make the grooves fit that much tighter. It's not as if you can just drop a song. You'd be losing a third of a side if you did that....
Plus add to that the Englander's phobia towards bass, (you only have to listen to anything done by the BBC, who just happened to set the standards of the time), and that would explain a lot.
Now I know that any fellow members from the British Isles would pro'ly wildy disagree with me, but that's because you have been conditioned for all these years to accept White Noise as opposed to the much gutsier Pink Noise as the standard. Well I've said it before, and I'll say it again, that's why God invented the Loudness and Bass and Treble Controls. So you can turn 'em up, and put some life and dynamics back into the music, even if it wasn't there before...... Nothing is definitive. Use a bit of imagination when listening to your music. It doesn't have to be 'Flat'. Flat goes nowhere. The world is not flat. Neither should be the music...
See wot happens when I stay up past my bedtime?
Blah, Blah, Blah, Blah, Blah....
Going going gone......
