KorgBA40 Bluegrass Tuner for Mandolin, Fiddle, Banjo and Resonator Guitar

I have two Korg tuners, one that is versatile for any tuning and frequency and... this one.This tuner is made for standard tuning only. If you want to tune your guitar differently - for example Drop D tuning or open D tuning, this is not the tuner for you. It will require changing settings between strings.On the plus side, it has an input and output and can sit on your line while playing live.

Didnt have the E9 tuning that I bought it for.

The Korg CA-40 Electronic Chromatic Tuner has wide range that covers A0 (27.50 Hz) - C8 (4186.01 Hz), you can tune a variety of instruments with the Korg CA-40, including wind, string, and keyboard instruments. The pitch and range are detected quickly and accurately. You can use the built-in high-sensitivity microphone to detect the pitch of an acoustic instrument without the need for any other equipment. Alternatively, you can use the separately sold CM-100 contact microphone to send the vibration of the instrument directly to the tuner, so that you can tune accurately without worrying about other sounds in the environment. An output jack (bypass) has been added to this digital tuner, making it easy to check the tuning even while you perform.Conveniently thin and compact The pocket-sized CA-40 features a refined design with a stand on the back that lets you place this digital tuner on any surface.Large, high-precision LCD meterThe CA-40's display has been enlarged for even clearer visibility. In addition to providing both the accuracy of an LCD and the easy viewing of a needle-style meter, red and green LEDs are also provided to indicate pitch deviations, making tuning smooth and easy.Sound Out functionIn addition to letting you tune visually using the meter, this digital tuner provides a Sound Out function that plays a reference tone through the internal speaker, allowing you to tune by ear. You can adjust the reference tone in semitone steps over a range of C4 through C5 (one octave) to accommodate a variety of instruments. Since the reference tone you specify is remembered, it's easy to sound it again whenever you need to.Adjustable CalibrationThe Calibration function of this hand held tuner lets you adjust the pitch in 1 Hz steps over a range of 410 - 480 Hz in order to accommodate a variety of concert pitches, giving you the flexibility to tune accurately to any song or key. There's also a memory backup function that preserves the Calibration setting and Sound Out settings even when you turn off the power.Auto Power Off functionThe power of this digital tuner will turn off automatically if the unit is left powered-on for 20 minutes without performing any operation, avoiding unnecessary battery consumption.Approximately 85 hours of continuous useThe CA-40 is designed for long battery life, and allows approximately 85 hours of continuous use (continuous A4 input, Meter mode, zinc-carbon batteries).* Even if a sound is within the detectable pitch range, detection may be unsuccessful for instrumental sounds that contain a large number of overtones or decay rapidly.** The calibration setting and the Sound Out reference pitch are remembered even when you turn off the power. However, when you replace the batteries, these settings will be initialized to the default values; the calibration will return to 440 Hz, and the Sound Out reference pitch will return to A.A great product. Will recommend again.

This is an excellent tuner. It's a fine choice for a band or orchestra instrument, where exact intonation is under the control of the performer. It is accurate, responsive (will lock onto staccato notes), can produce a user-selectable reference tone and can be calibrated in 1 Hz steps from A=410 to A=480.The last-selected calibration and reference tone are remembered when the tuner is off, until the batteries are replaced. Unlike some tuners, the reference tone is a tone, not a buzz. A good optional clip-on microphone is available, but the built-in mic works fine unless there is a lot of ambient noise. Small enough to fit in most instrument cases and sits securely on a standard music stand.A close look at the display will reveal the needle moves in 2-cent increments. That means, assuming the electronics are perfectly accurate, this tuner will show anything between +/- 1 cent off the target pitch as perfectly in tune. That's a trivial difference for most orchestral and band instruments, because the performer is continuously adjusting intonation by ear, over a much greater range than +/- 1 cent.However, it's not ideal for any instrument where intonation is relatively fixed, such as a guitar, because many trained musicians can hear a difference in the .3 cent range. Bottom line, a chord played by a guitar tuned solely with this or any other low-cost electronic tuner will sound out-of-tune to many people. As your ear develops, it will sound worse.You could fine-tune by ear once the instrument is rough-tuned with the tuner. Or, better, tune one string to match the tuner's reference tone (or a  tuning fork ), then tune the other strings to each other by ear.Technicians and studio musicians who don't want to tune by ear often use a strobe tuner, such as those made by Peterson or Sonic Research (most other brands are ordinary tuners with a strobe display). These are more accurate than most musicians can hear, are expensive, and take a day or two to get used to. Korg LCA-120 Focus Tune Chromatic Tuner with Large Backlit LCD  performs almost as well as a strobe tuner for a lot less money. Its Focus Tune feature automatically switches the full display from +/- 50 cents to +/- 10 cents, so the display resolution becomes about .5 cents, 4-times better than the CA-40. Most musicians would be satisfied with that. It also has a larger display with back light, adds jacks for headphones and external power, and volume control for reference tone. It's bulkier, unstable on a music stand, and probably more likely to be damaged if dropped. So I prefer the CA-40 for orchestral instruments, LCA-120 for guitar, and a certified technician with a good ear for piano.Another alternative is free software: TB Strobe Tuner. It's as accurate and precise as a real strobe tuner, and probably easier to use, provided a computer with a mic is handy.

Best tuning product for any instruments

ottimo prodotto

I bought this tuner to use with an acoustic guitar and found it very straightforward right out of the box. The front of the fascia includes an on/off button, a small microphone and a swinging needle. When you play a note into the microphone the tuner displays the pitch of the note in Hz to the left and also the name of the note to the right; the named note is the one nearest in pitch to the note you played. If the note is off pitch the needle will veer to right or left of its centre position and a red light will display. When the note is adjusted to pitch, the needle will be aligned on its centre zero position and a green light will display. Using the needle alignment to tune an instrument is very easy and I had my guitar tuned in less than a minute. Since then I have been using the tuner regularly and it's become indispensible. You need to prop up the tuner when using it and there is a little flip out lever at the back which acts as a stand - it's fine for this purpose. I have not used the tuner long enough to assess its battery life - this is claimed in the instruction leaflet to be approx 85 hours. All in all this is the best tuner I have found and I prefer it to onboard or clip on tuners. The tuner is powered by 2 AAA (3V) batteries which are easily obtainable. Great value for money.

Es ist einfach zu händeln, meine Tochter stimmt ihre Gitarre nach einmaligen zeigen ganz alleine

I chose this tuner because I had heard some pretty good reviews about it. And I can safely say that it is really good. It's not the best tuner out there by far, but for it's price, it's totally worth buying.I use it to tune all of my guitars (2 electric fenders, 2 acoustics - no idea what make - and my stagg bc300 bass guitar) and I find it really easy to use!When using a cable to tune the electrics and the bass, it works a treat as there are no interferences that will affect the true tuning (I know that made little sense) so no background noise affect it. This makes it really effective.It's not 'amazing' when using the microphone though as background noise is picked up quite easily. Just make sure that there is no background noise when tuning and it's pretty accurate.It's much easier to tune my guitars now than it used to be, so it really does work - it's worth the money. And it's great value too!
