Memory lane! There are several of those lying about here, including a couple of the old brown ones. They sort of match my (used every day) Simpson 260 VOM.

Not being a music major, I missed the day where they show you how it works, so the one I saw once or twice back in the '80s was just pale orange psychedelia. But this one looks fundamentally different, like it lights up on a sort of pitch dial position, where the one I remember was equally bright all the way around.

I have an android stroboscope tuner app on my cellular phone, but best as I can make out, it doesn't have any useful features beyond an ordinary tuner app. Not that it has much to go on, as I'm sure the builtin mic is not much.

Strobes are so much better than these cheap digital tuners we use today, which are frequently wrong. These are the real deal. Wish I had the cash and were up in Oregon...

You realize that there are many quite accurate digital implementations of this concept, correct? Ranging from pretty decent cell phone apps to, say, the Petersons.
