Is take it apart!
I’m utterly confused why EHX hasn’t been putting LED indicators in the Frequency Analyzer all these years. They are just now coming out with a new model that does, but the one I got is the giant box that you typically see. But I knew you could add an LED pretty easy, so with some help from some Harmony Central guys I wired up a pale green LED in the chassis of my crazy sound box.

gut shot - look at all that wasted space!
