Worth every penny.

This thing makes every guitar sound better because of its extreme accuracy. It picks up low notes far better than almost any other tuner. The only thing about I don't like is that the power input is on the side, instead of the top, so it can be a bit of a pain to get another pedal snugged right up to that side of the tuner.

Once you get used to it, there's no going back.

Used a chromatic tuner all my life. But the strobe tuner's accuracy is pretty visible. A/B'ed it with other tuners, and this always comes on top. Love it and won't ever leave it!
