That’s the same point the author was making. And it’s not just limited to descriptions. Record labels, track names, genre names, sometimes even DJ / artist names have taken their “acid” name from the distinctive sound of the TB-303.

Obviously it will depend on the era and scene too. Eg if people talk about acid in the 70s Prog Rock scene then it’s not going to be about a hardware synthesiser built a decade later. But if you’re talking about dance music, then “acid” refers to 303 more often than it does the drug.
