Help for aTin Ear May 28, 2007
Richard L. Steiner (OREGON United States)
65 out of 66 found this review helpful
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.
really fine tuner April 6, 2008

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.
Very pleased with this tuner! May 21, 2007

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?

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.
Excellent tool for tuning a piano June 9, 2009

Let me start off by saying that I have never owned a stringed instrument until a friend recently gave us their piano. It's obvious that I knew nothing about how to tune them. I did a little reading and came across this device and some other sites that had some very basic "how to" instructions.
When my son wanted to take piano lessons at home, It was clear, even to my ears, that it was severely out of tune. The person that we got it from had it in direct sunlight for hours a day and had not tuned it in over 4 years. I decided to get one of these and have a go at tuning the piano myself instead of paying someone else $50 each time.
The first obstacle I found was getting the proper wrench for the square 1/4" pegs used to adjust the note of each key. After looking around, nobody local had a square socket. A small wrench would just slide off, so that was no good. It does require some torque to adjust the strings. Then it struck me - I have sockets for different size ratchets, which includes a whole socket set with a 1/4" square opening on one side. I took my 3/8" breaker bar and used a 7/16" 12-point socket backwards, and viola! Piano tuning wrench! It worked very well, too.
Off to tuning the piano. Fortunately, I had ordered some mutes (rubber wedges) even though I didn't know what they were for. I saw many auctions for them, so I figured they were importantant. They are. For the lower notes, they were just one string each so no mute was needed. Then about a third of the way up the keys, each note was made of two strings. You need to put a mute on one so you can tune each string individually. The higher third of the keyboard has 3 strings per key which takes two mutes and patience to get tuned correctly.
This tuner did a fantastic job except for one area - the lower 6 keys or so. It did say in the owners manual that it may have troubles with very low and very high notes. So I just tuned those to sound harmonious with the middle keys that this helped me dial in.
On a few keys, the note would jump around, like from C to F# to B and back to C. It probably had to do with where I placed the unit, but I didn't have troubles with several of the other keys.
The green LED lights when you've hit the jackpot, and the LCD display shows you how far off it is and what note you just played. It can do some other things, but I just used it to help quickly get this piano in tune.
After about 2-3 hours of patiently tuning each key, I was done. My son's piano teacher said the tuning job was pretty good (pat myself on the back.) It's certainly not a concert-grade job, but neither is that really old piano.
For the price of this, you just can't go wrong. It so easy, even this first timer felt confident in using it.
