I've yet to come across anyone's reasoning behind this, so I'm guessing there is none... but why do people label ads for Ludwig classic lugs as being specifically bass drum or tom lugs? I'm assuming it's to catch the eye of someone who's looking to outfit a specific shell, and has nothing to do with the lug itself.
Same thing with stands. They're never just selling an early '70s Atlas snare stand, it's an early '70s Atlas Vistalite snare stand.
There's not really any difference between this stuff, right? It's just like including Bonham in an ad for an LM402, or a 18x16 floor tom.
