Call the HPF a speaker protector or distortion destroyer or rumble reducer or mud masher or some other more colorful name.
People will understand.
AND, you can hear what an adjustable HPF does.
I had a guitar player who would have scoffed at the very idea of adding a HPF to his rig. "But it messes with my tone!" His
precious tone... so thumpy and bottom heavy I may as well have not showed up to practice at all most days.
The rest of us all did everything we could to get him to turn down the low end on his amp, but he was downright indignant about it. And this is a lifelong friend of over 30 years that I've literally been playing music with for almost 20.
I would get to practice early just so I could tweak his EQ ever so slightly each day. Just a hair so he wouldn't notice... everything was going fine until I realized I was adjusting the wrong channel all along.
I even went so far as to buy a Tubescreamer, famous for it's low-end roll off, and gave it to him as a gift. He hated it because it "sucked out all the beef" from his precious tone. Beef which was messing up our entire mix and causing everyone to have to turn up to be heard. I even contemplated hiding my Broughton in the FX loop of his combo, but couldn't figure out how to power it without him noticing.
Somehow I talked him into buying a Telecaster, which was at least clearer and brighter and less bassy than his humbucker-equipped guitar. But cutting low end at the amp... absolutely out of the question! Turning down the gain and playing cleaner? Even more out of the question!
Oh, and to top it all off, he loooooved using his neck pickup for almost everything. Mud city!
So I would say no, not everyone will just magically understand. Most people have a very pre-conceived notion of what they
think they should sound like, and everyone else, and the mix they rode in on, be damned.
My greatest joy in that band was highpassing the crap out of his guitar tracks when mixing our basement jams. "Oh yeah! Sounds really great! Nice work on the mixing!"
