I keep my EQ settings noted on a scrap of paper just in case of data loss.

I agree that a way to back up and restore EQ settings would be nice. Unfortunately, we don't have that yet.

However, this is different than asking for a "ready set" EQ curve that's already been pre-programmed for you. I've seen car stereos with these before (presets named Jazz, Rock, Classical, etc.), and they are just silly, they're missing the whole point of EQ.
