I also use the Korg Orchestra tuner, and like it quite well. The only drawback is that the speaker is in the back, so if it is on your stand facing you, and you want to tune to its pitch, it is muffled. Korgs are always good for producing a pitch that is easy to tune to, and it meters all the strings, though you may have to move the pick-up. It doesn’t come with an adapter, which is worth paying for, as batteries only last about 3 months. I do not use a suction cup pick-up on my sounding board, it leaves a mark.
