as 008 pointed out, EQ presets are all but useless, and the argument could be made that that is ESPECIALLY true for people who are just starting to learn.
for example, how helpful would it be for an engineer just starting out to record some vocals, add an EQ preset for vocals, and think "hey, this is how it's supposed to sound!" even when the preset isn't at all appropriate for the vocal sound they've got going on in context with the rest of the mix?
your answer may be "well, their ears will tell them when it's bad, and they can make changes!", to which I'd have to say, that's what they should've started doing in the first place.
