Korg CA-50 Chromatic Tuner for Orchestral Instruments w/ Memory Backup and Auto Power-Off Function

I’m a professional musician, and I’ve owned Korg tuners for decades. I recommend them highly to students, amateurs and the professionals. They are accurate, sturdy (I’ve dropped mine on the floor many times with no damage), lightweight and batteries last a long time in them, unlike some other brands of tuner. This model is a tuner only; no metronome is included. I actually used to use the Korg combo of tuner and metronome, but that model goes through batteries a lot faster, and the metronome isn’t loud enough. My current favorite set up is to have the Korg chromatic tuner (no metronome) plus the Seiko quartz metronome model SQ50V in my bag at all times. The batteries last seemingly forever and they’re reliable, sturdy, and top quality, at a reasonable cost. I don’t want to use my phone for tuning and a metronome unless I need a back up for a very brief time., and is used only for a very short time. I don’t want my phone out in rehearsals, concerts and practice times. Have top quality in the Korg instead. Really, this is the best.

I understand why many orchestra musicians in past used it, it works very well even today. I took my viola to the luthier to put on some new strings, when I played the notes wasn't in tune. I used this Korg CA-50 and it plays perfectly now. Other reviews for newer versions stated that this one was better.

Easy to use. Small and compact size. Useful for tunning.

I had a Korg tuner for over 25 years and somehow lost it somewhere, so I needed new once to tune my harps to. This one works well and is every bit as good as my old Korg. It is pretty accurate and makes tuning a breeze. No complaints

KORG MAKE GREAT PRODUCTS , I STILL HAVE MY 25 YEAR OLD KORG CA-30 AND IT WORKS GREAT. I EXPECT THE CA-50 WILL MAKE IT 25 YEARS ALSO . UPDATE A LITTLE MORE "JUMPY" THAN MY OLD KORG TUNER .

These little KORG tuners are somewhat of a best kept secret. They tune really well, have a jack so that if you need to tune in a noisy environment you can do that. The display is easy to see, even if the light isn't brilliant. The tuner isn't very expensive and is comparitively cheap to. They also have the feature in which you can flatten or sharpen the root note, so you can keep all strings proportionally sharp or flat, which is cool if you're trying to replicate a particualr sound or version of a song precisely. They don't chew batteries and the batteries can last for a pretty long time if you tune and turn off. Don't drop them, I had my previous one for about ten years and replaced it because I dropped it and broke it. UPDATE: It turns out that whoever manufactured the one I had for ten yeas either isn't still manufacturing these or have lowered their quality standards significantly. The new KORG tuner isn't anywhere near as good as the previous one. I'd go so far as to say that this tuner is fine as a tuner for electric guitars because the input is direct and not through the mic. That does make it a bit inconvenient to use because one either needs a spare cable out and available for tuning or one needs to turn the amp up or put the tuner right in front of the amp. Not useful for gigs. Also the accuracy of the tuner is questionable, If I tune the guitar using this then using another tuner I need to re-tune the guitar. If I compare the other tuner with a third brand I don't need to re-tune the guitar to fit in with the third tuner. Upsides, it's cheap,

Works really well. Not only tells you if its the right note but also how far you are from the note - makes it easy to tune a flute.

I like the product because it is accurate. However it is a little difficult to remove the cover to remove and install the batteries.
