This is a true strobe tuner equipped with the Buzz Feiten system capability. It's a little weird to get used to at first, but after I did it was awesome. It's built like a tank and accurate as hell. Great pedal!
You can tell this pedal is well-made as soon as you pick it up. It's really, really heavy, and it's good looking too. Problem is that it's not as fast as the other pedal tuners and the whole circular thing instead of the classic polytune styled tuning is irritating. Not good for on the fly tuning at all.
