Korg CA-2 Chromatic Tuner (CA2)

I purchased this to set intonation on my electric guitars - I don't have a tuner pedal and clip-on tuners or phone aps don't seem reliable when playing the 12th fret. This is perfect and I'm now spot-on with all my guitars!

This is a great little tuner. I use it for my ukuleles, even has a port so you can plug in the electrics. Very easy to use, and easy to read. Be sure to verify the calibration. Mine periodically gets bumped off 440 when I throw it in my bag.

This is my second Korg tuner. The first one is still working after 20 years, but I wanted one that did more than just guitar open strings. This CA-2 is just the ticket. Popped in the batteries and set the two tuners side-by-side and they both agreed *exactly* on pitch. The needle jumps around a little if you let all the guitar strings ring, so mute the ones you're not interested in and it's rock steady. I tried it with the 1/4" jack and with the microphone and both worked beautifully. The only downside: The ugly yellow plastic on the front and bottom. Makes it look older than my 20-year-old original. Fortunately that's an easy fix: The yellow panel pops right off and a squirt of satin black paint fixed it right up. This is a great tuner. Worth twice the price, easy.

I got this assuming it might be better than my iPhone for some reason, and I was wrong. It responds more slowly and has more coarse demarcations, meaning I almost always just whip out the phone when practicing. The Korg also jumps around quite a bit, maybe picking up on harmonics instead of the fundamental note being played? Which is more of an annoying inconvenience than a deal breaker. However! The ability to plug in directly is its saving grace. You can get in tune with reasonable speed and ease no matter what the volume level of your surroundings is. For this alone I recommend it, but if you're just playing in a quiet comfortable practice setting, skip it. As a final note the mic is not great at picking up the low E on a bass, though this is a non issue when plugged in. I can imagine it might become unusable if you have a 5 string.

This is an absolutely solid, reliable tuner, that does what it is supposed to do, without any fuss. Although I use other tuners, on my phone, in software-etc, it is always a great idea to have one of these units stuffed away in your guitar case or gig bag. An essential piece of gear, for professionals and hobbysists alike.

For those that miss the old needle, analog style tuners, from the late 80's, early 90's, this is a really great digital version. Within the past few weeks of receiving it, I've put it next to many other tuners. It is very accurate. I have a Snark that I often use. However, trying to get accuracy out of it when doing a set up, and intonation is hard at times. It would give me good open string readings, sometimes 12th fret, but hardly ever harmonics. This tuner got past that issue. It came brand new in a box, with simple instructions, batteries included as well. Beyond a great deal for the price. It's also pocket size, which makes it easy to stick in a case compartment, or gig bag to take on the go. Also, the open mic feature is really nice for horns, or other vocal instrument, that has no cord access. It is also very accurate as well.

Very Functional and good response. I use it all the time.

And so I continue on with my love of weird, niche things. My instrument of choice is not something like a violin, guitar, or anything you would commonly find; it's plucked psaltery. I got mine over a year ago and just let it kinda languish. However, I decided to pick it up and get it in tune. Tune apps on my phone just left me feeling confused and I wasn't sure if they were accurate or not. This little thing saved my life. It's really simple and easy to use for a novice. I would personally have preferred a clip on with lights, but honestly, this works fantastically. Plus, it's small enough it easily slips into the front pocket of my case without being overbearing.

Ottimo per accordare le Highland bagpipe

Funciona de maravilla

Good cheep tuner for intonation. 100h battery time. Can't go wrong!

I love this tuner. It makes tuning my esraj quite easy. But at this price, it should have come up with a metronome.

I was sort of sceptical at first looking at the price of this unit, I still don't understand why it is so 'cheap'... I was wanting a tuner to tune my guitar for drop C and C# and this little guy fits the bill. I was not sure at fist if it would pick those notes up, tho it will pick anything up I ever have to tune for. This unit is perfect, comes with batteries, I love the microphone or plug-in option, and it is deadly accurate and has you tuned up within seconds (if your guitar is semi close) to get you going to play your favorite songs IN TUNE. I also like the fact that I can position it right on my guitar to get all dialed in, it is clearly visible, simple and makes it fun!
