Screen lights up green when in tune, LED's are very visible on a dark stage.

Can see on dark stage well or in a lit up practice room

When tuning on a dark stage before a set, the red and green lights are super bright

Tracks the notes pretty well and the display is very easy to read on a darkened stage

I like how the light remains a solid green when you are in tune makes it very easy to see on a dark stage

The LEDs are easy to see, even outdoors on a bright stage

This pedal is VERY EASY TO SEE on a dark stage, it's very bright, and pretty darn accurate!

Red and green LED’s to indicate sharp or flat plus led bars on the display to indicate the same in more detail.

Works as it should.

It works as it should.

Finally, it just stopped working for the higher strings (G-B-E) altogether.
