In my case it was a bit of analog outboard clipping. Boomy bass can certainly eat up headroom in the manner that would cause that to clip, Simon has the low bass rubbish cleared out, so it's really just an issue of the outboard metering responding late to transients, which is to be expected.
Just for clarity's sake, so that others aren't misunderstanding your contributions, I'll point out that the 30 hz buildup you've lit onto isn't a fundamental, it's a room resonance. Musically useful fundamentals aren't generally going to occur beneath 50 hz, mainly because human ears aren't able to hear beneath that range very well. Even at 50, it's mainly a feel thing more than something you actively hear in the mix. I'm not really a stickler for terminology, but in this case the distinction is important, since fundamentals are musical and sub (usually) isn't.

I'm grateful for comments and suggestions. Thank you for listening!
