«  Not for me. »

I've had it for a year, and I had the tuner korg (black foot). And in between I have kept the Korg just because I had not concentrate to watch the LED. PolyTune is satisfactory in the room in darkness, but if too light, or even a little it becomes galley to see the light. And that is disqualifying in my case.
Since I was not covered by other modes offered by this pedal, I am separated. Plus I've always had a little doubt on the accuracy.
So in one another, saving time that is supposed to bring this pedal was not obvious to me ...

Pros: sturdiness, enjoy some operating modes.
