Nice Stealth Tuner
Reviewed in the United States on May 24, 2016
I love these little tuners. I had bought one previously for my mandolin and I like it so much, I bought this pack of two more to put on additional instruments (I have a little mandolin-buying problem, lol). I find a good tuner to be really necessary. I can tell if something's out of tune, but I have a hard time telling which way it's out, and with mandolins, each pair of stings need to be right on, or things sound really wonky.
These clamp easily onto the headstock of a mandolin. I attach them upside down, so that I can see the tuner indicator from under the headstock and all that shows on the top is the little flat top of the clamp. Much nicer looking than the round tuners that stick up on a flexible neck (although I have a few of those too, and they work well - just don't look great). There's a little button on the unit that flips the digital display, so it still reads right-side-up if you install it on the under side of your instrument, like I did. I was complimented by a fellow mandolin player recently on my ability to tune by ear. He didn't see a tuner, so he thought I wasn't using one. I laughed and flipped over my mandolin to show him my "stealth" tuner.
These tuners work well. I've tested them by using them at the same time as two other types of tuners and they showed the same results. If the note is right on, the letter will display in green with one bar on either side. The letter changes color if the note is out of tune and the number of bars to the left or right of the letter increase, depending on how flat or sharp the note is.
