"Seesaw" EQ

i always thought a "tilt" control was just a sweepable bandpass filter, where you could sweep it til it "sounds good" like a mid contour kinda deal.

From the ESP website:

"10 - 'Tilt' Controls

Finally, there's one last tone control arrangement that was popular for perhaps 5 minutes or so, sometime in the 1970s. It was used in at least one Quad preamp as well as a couple of others, but it died out fairly quickly because it's not really very useful. The effect was to literally tilt the frequency response, so if the bass is boosted, the treble is simultaneously reduced and vice versa. I'm not entirely sure why anyone thought this was a good idea, but it's part of tone control history, so is included."

Isn't the Big Muff tonestack a kind of passive tilt (plus a mid scoop)?

Yes or no.

The "point" of the hi-fi tilt control is "NO" effect in the middle of the audio band. It only adjusts bass versus treble.

The Muff really aims so one way cuts all bass, the other way cuts all treble, and mid-turn does less. But as an incidental thing the mid-turn does wind up with a mid dip. It is perhaps not elegant for pre-produced music reproduction. It has proven versatile for music creation, warping the nasal midrange tones of naked steel strings into other flavors.

The deficiencies on HiFi systems usually happen at the ends so Bass/Treble controls work fine.    Tilt doesn't really fit and where it does fit the Bass/Treble controls will do.

I remember a few HiFi amps had Midrange controls.  They disappeared quickly as well but made an appearance 20 year later on cheap junk "HiFi" systems - the one's that have the Wide Stereo buttons.
