Precise palm-size tuner.

Tuning comes full circle
The DT-4 is a unique style of chromatic tuner in which LEDs around its circumference indicate how close the input pitch is to the note name displayed in the center. In spite of its compact size (it fits in the palm of your hand), the illuminated circumference and large note name display provide excellent visibility, allowing high-precision tuning over a range of A0 (27.50 Hz)-C8 (4186.01 Hz). The adjustable calibration lets you specify the reference pitch in a range of 410 Hz-480 Hz (1 Hz steps). Its design emphasizes comfort and ease of use, with function-selecting switches placed for quick and easy access.

Three new tuning modes
The DT-4 illuminates the green LEDs around its circumference in one of three tuning modes: Strobe, Mirror, or Meter. There are also triangular red tuning guides that indicate whether the input is sharp or flat, helping you tune your instrument more precisely.

Strobe mode
The green LEDs will stop moving when your instrument is in tune. The LEDs will move in a clockwise direction if the pitch of your instrument is sharp, or counterclockwise if it is flat. When the tuning is correct, the two tuning guides will also light simultaneously.

Mirror mode
Mirror mode is a new concept of tuning found only in Korg tuners. When the two dim green LEDs at the lower left and right coincide, you're perfectly tuned. The bright green LED will move to the right of center if the input pitch is sharp, or to the left if it is flat. The distance between the bright green and dim green LED's indicate the distance to perfect tuning.

Meter mode
Tune your instrument so that the bright green LED is aligned with the red tuning guide in the center as on a conventional needle type tuner.

Designed for easy operation
The DT-4 is designed for effortless operation, with switches conveniently located when held in the palm of your hand.
In Strobe mode if approximately thirty seconds have elapsed without any audio input, the rotating red LEDs will go dark. If approximately ten minutes have elapsed with no audio input while powered-on, the DT-4 will automatically turn off to prevent unnecessary battery consumption.

I can see it!

I've just received my tuner today and it the BEST tuner out of the half dozen that I've owned. It's small but highly legible in the dark. The DT-4 large, colorful displace is very easy reading for these aging eyes. It fun to keep it turned on while playing. Cheap light show. It's also inexpensive. Go buy one, in fact buy 6, one for each string. That would look real purty on a darken stage. I guess the only con would be that a guitar can be plugged in but there is no out to an amp. Doesn't bother me

Want to be perfectly in tune for once?

Get this little tuner. I own about six tuners, and have owned others besides -- but this is the first one that, in my opinion, provides a fast, hands-free, no fuss, dang-near-perfect tuning. After tuning my guitars with the DT-4, I often find myself sitting and just strumming slowly a chord, TRYING to hear one string that isn't in sweet harmony with the others -- and I never find it.

The thing that makes this tuner THE tuner is the "no guess work" way it tunes your instrument. The three different "modes" (ways) of tuning are childishly simple - just select one and pick a string: you'll see immediately what's going on - and these three ways of tuning are all, each one, good enough by itself. But you get three! At least you can triple-check if there ever *is* any doubt. I can't get over how FAST I was able to tune my guitar to virtual perfection, first time I used this tuner. Less than a minute and bam.

Just keep it in your pocket, because you can bet that sticky fingers will itch to get a hold on this little wizard from Korg. Get yourself one; enjoy your instrument exactly the way it's meant to sound. In less than a minute.

Best Acoustic Tuner I Own

Posted by Texscratch from Central Texas on Jun 26, 2009

Reviewer's Background: Hobbyist; occasional gigs

Reviewer's Play Style: Americana, folk, country, early rock

I go through tuners lick crazy; always looking for the perfect one. I stopped buying others when I found this one over one year ago. Hands down the most accurate chromatic of eight tuners I've owned/used. Absolutely fantastic for six or twelve stringers. Dependable and rugged enough to survive many oops drops...

I've had this little dude for a couple of months and I love it. Its smaller that a can of dip. Its easy to use and VERY easy to read. Built in mic. I have always had great satisfaction from Korg products. I have a Korg rack tuner and this little fellow rivals its precision. I choose this product for price, brand loyalty, built in mic, and strobe display. I use it for acoustic work mostly.

Best tuner I have used

Reviewer's Background: Teacher and performer

Reviewer's Play Style: Classical orchestra, rock and jazz

I teach string instruments in Middle and High school orchestras, as well as play gigs on guitar and bass on weekends. Over the past 20 years, I have tried at least 10 different brands and models of tuners with my students and my own gear. I believe this Korg model outshines them all. The strobe method works incredibly well. It tuned my violin and string bass, locking in quickly with the mic. My electric guitar and 5 string electric bass tuned very quickly direct into the input. The display is easy to read, very bright, and it handles the range of a bass low B through the violin high E no problem. I plan to order some for my school.
