Customer Reviews
Very pleased with this tuner! 
2007-05-21
I just purchased one of these little tuners from Amazon last week. Though my guitar is low quality, (that's the next thing I'm going to buy) tuning it using only the meter mode of the tuner made it sound quite good, much better than my ear tuning. This thing is sensitive, accurate, and incredibly easy to use. What else do you want?
Wonderful tuner 2007-01-12
I really like this product, especially the back flap that opens as a stand.
the tuner is sensitive and easy to operate as well.
Very sensitive 2006-07-04
This tuner works fine and is worth the small amount I paid for it. It is very sensitive. I have to turn the cooler (which plays Bb) off before I use it. One drawback. You must shut it off when you're done, otherwise it will be ruined. I have another tuner that shuts off automatically. I always do shut them off, but I prefer the safety feature. Both tuners are accurate, simple, easy to understand and use.
Sensitive enough 2008-06-22
I have two autoharps to tune. That is 72 strings in all. Sometimes it is difficult to pick up the low strings with other tuners, but this one does the job just fine. Easy to read display, even for old eyes. Nice and light and easy to take with you. Battery lasts a long time.

Got mine from Music Bay. I highly recommend this Company to do business with. Very fast shipping and product is excellent to use. It is very sensitive and compact. Thanks John
Easy to use tuner 2008-04-08
I use the tuner for a six-string acoustic guitar. It worked well right out of the box. I just popped in the included batteries, pressed the "on" switch and the unit did its thing.
The only shortcoming I've found has nothing to do with its function. There is a small fold-out support piece built into the back of the unit to aid in standing it in an upright position; it works fine on a hard, level surface but is virtually useless on anything else.
really fine tuner 2008-04-06
I'm a professional classical musician, play viola, and use this every day. I usually use it with the Korg CM-100 tuner clip, which makes it even faster and more accurate, faster and more accurate IMO than the KORG OT-12 which costs much more. I also find it more accurate than the CA-30. It can easily track one note per second, and if my pitch is very accurate so it doesn't have to hunt much, it can even zero in in half a second, so I can actually practice passages with it. Batteries last a LONG time. A truly excellent tuner.
Help for aTin Ear 2007-05-28
I am not a musician, but I love "playing" the ukulele as a way to amuse myself and relax at the end of a long day. Unfortunately I have trouble tuning my instrument because I am not so blessed with a tin ear. I have trouble determining when I have my uke strings in tune. I can get close, but often an off pitch string sounds OK to me.
I really never heard of an electronic tuner before I discovered the Korg CA-40 as a recommended product based on my purchasing history on the [...]. The price tag on the thing was so cheap I thought I could buy one and gamble that it was a remedy for my problem tuning the ukulele.
The tuner arrived and I was amazed at how easy it was to use and how nice my ukulele sounded once it was tuned properly. The Korg CA-40 "listens" to a string and an easily read screen along with a series of lights tell me what note a given string is sounding. The device automatically shows if a string is sharp or flat so I know to tighten or loosen it on the way to the proper sound.
I read some reviews of the Korg CA-40 by real musicians and was quickly intimidated by jargon and comments I didn't understand. I thought the tuner might be something a genuine amateur would find overly complicated to use. Not so--actually the tuner is probably more useful to a novice with a dumb ear than to the pro with perfect pitch. This thing is a winner.
