I needed a good pedal tuner and this one is. I did a a/b with the Boss TU-2 for a good 30 minutes and this was much better IMO.
First off it is easy for me to read the notes displayed, simple operation and no loss of tone or volume when off and no pops or anything when engaged and dead on accuracy +/-1cent with 4 display modes and true bypass.
The Boss on the other hand was decent but did not work well in flat or double flat modes. It worked best in chromatic mode and there was some loss of tone when off.
I do have two Boss pedals that I enjoy, but in this case the Korg was the big winner.
I am sure there are other threads on this, but I wanted to share my findings on these two back to back
