Great Tuner, but HZ Feature Not Very Useful.
This is a highly functional and stable tuner, with a great display layout. I'm able to lock right in on correct tuning by eliminating the blinking red (flat) or yellow (sharp) indicator bars. Fits well on the guitar and bass, and really easy to use. I haven't yet used the pitch change feature, but that will be very useful when playing against a particular organ that's known to be a couple of cents flat.
I am NOT, however, very highly impressed with the "HZ" feature. It can only be used to display frequencies for the six guitar notes, EADGBE, and only in that order. I paid a little extra for the HZ feature thinking that it would give me extra precision for general needs, like checking intonation at several different frets on the guitar, or truing up that one bad F string on my son's piano. However, I can't do those things. Just knowing the pitch of my guitar's six strings down to the nearest Hz doesn't help me in any significant way. So, HZ will probably stay turned off pretty much permanently.
Looks like I should have gone for the regular Super Tight tuner without the HZ feature. In hindsight, that would have been a great choice.
