It has to do with the EQ bump of tape. I think it has a slight boost at 50hz and it is 100hz at 30ips.

When I was a kid I'd make overdriven mixtapes with my dad's TEAC deck. I still miss that sound.

Seems like the Neve portico-5042 does all of this. Giving the tape saturation to the music.

Me! I have 4 Nakamichi decks for this reason. 500 x 2, 550 all with the dual tracer and focus gap heads. RX505 tri tracer auto-reverse with the Sanyo transport too. They all sound different and lovely. Cassette fuzz is way more heavy-handed than on a reel to reel though. When you record your own tapes you can set the bias which changes the saturation character. But it is heavier odd-order.

Cassette does not go 15ips, not even 7.5. Cassettes are so odd with the formulas and the pre-post EQ curves to try to eek out linearity. Nakimichi even made up their own pre-post EQ that was far superior, but you need a Nak to play it back correctly.

Nak 680ZX can record half speed cassettes, something i drool over regularly

Found this in search of a source with a nice pattern.

Maybe there is light at the end of the tunnel?

That kind of makes sense. If you think about it, a tape head and tape is kind of like an isolation transformer. Matter of fact, the Neve analog tape emulator is just this...two coils really close together. It does other stuff like emulate the saturation, which maybe adding in some of those harmonics.
