A portable, pocket-sized tuning solution.
The CA-50: the standard tuner for orchestral instruments, now with even better visibility.
The CA-50 features high-precision tuning functionality and a slim and compact design. The new CA-50’s display is now, even easier to read. Long considered the standard in chromatic tuners, the CA-50 offers simple and intuitive operation and a satisfying tuning experience for every instrumentalist.
A wide detection range supports tuning for any instrument.
The CA-50 features a detection range of A0 (27.50 Hz) to C8 (4186.01 Hz). For wind instruments from piccolo to tuba, or string instruments from violin to contrabass, you can tune band or orchestral instruments of any pitch range. A high-sensitivity mic is built in, allowing the note name to be detected accurately even without a contact mic. By using the separately sold CM-200 contact mic, you can tune with confidence that nearby sounds will not affect the result.
Calibration function is provided.
The calibration function supports a variety of concert pitches. It can be adjusted in 1 Hz units in the range 410–480 Hz, allowing flexible tuning that matches the song or key.
Marks provided to indicate pure major and minor third intervals
The meter scale of the CA-50 provides marks that indicate pure major and minor third intervals. By tuning to these marks* you can play beautiful harmonies when you're in an ensemble. This is convenient not only in a brass band or orchestra, but also for vocal or a cappella practice.
* When matching a pure major or minor third, the note to be adjusted will depend on the music that you're playing.
Sound Out mode is ideal for ear training
The “Sound Out” mode lets you listen to a reference tone emitted by the internal speaker, allowing you to tune by ear. A reference tone in the range of C4 (261.63 Hz) to C5 (523.25 Hz) can be output. You can check the pitch using both eye and ear, allowing you to tune more accurately, and also providing an ideal method of training your sense of pitch.
Dramatic increase in battery life.
The CA-50 can be used for approximately 135 hours (when using zinc-carbon batteries). When the remaining battery capacity runs low, the display shows an indicator, letting you know that it's time to replace the batteries.
Reduced stress when using the unit on a music stand.
A new mechanism reduces the possibility that the unit will overturn, making it less likely that the tuner will slide off and fall when placed on a music stand. You'll be able to concentrate on your playing without fearing that the tuner might fall during the performance.
Memory backup function and auto power-off function provided.
The memory backup function remembers the calibration and sound out mode settings even when the power is turned off. (Settings are initialized when you replace the batteries.) The auto power off function automatically turns off the power when 20 minutes have passed without sound being input.
Stylish body design with excellent functionality.
The folding stand allows the tuner unit to be more stable on its own. The sliding battery cover is designed as a single piece with the unit itself, so there's no worry that the cover might be lost when replacing the batteries.

Acoustic guitars and ukulele are made of wood, and wood is sensitive to changes in climate. Shifts in temperature or relative humidity can affect your instrument in multiple ways, some of which can lead to costly repairs if you’re not careful. Solid woods in particular are especially prone to the effects of climate fluctuation. For example, extended exposure to low relative humidity (below 40% RH) can dry out the wood, causing it to shrink and run the risk of cracking. Similarly, excessive humidity can cause the wood to absorb moisture and swell, potentially causing other problems. Without adequate humidity control (especially in drier local climates), acoustic instruments can crack and their necks can warp, causing problems with fretting, intonation and playability.
So how do you prevent this kind of damage? Easy: by keeping your guitars and ukulele properly humidified (ideally between 40-60% RH). The easiest way to do this is by storing your instruments in a case with a case two-way humidifier inside. A two-way humidifier will slowly absorb or release moisture inside your case, maintaining humidity to help ensure your instrument doesn’t suffer damage. Using a digital hygrometer can help you monitor humidity levels around your instrument.
Symptoms of a dry acoustic instrument:
- Low action. Strings are very close to the fretboard.
- Hump on the fretboard where the neck joins the body.
- Sunken top across the soundboard between bridge and fingerboard.
- The back of instrument looks very flat when it is dried out.
- Sharp fret ends extend beyond the edge of the fretboard.
- The plane of the neck angle on a dry instrument hits above the top of the bridge.
Symptoms of a wet acoustic instrument:
- High action. Strings that are unusually high off the fretboard, making it difficult to play.
- Unusually swollen top
- Unusual warp on the top, back or both at the end-block
- Improper neck angle. Sighting the neck to the bridge, the frets will appear to hit below the bridge.
The D’Addario Two-Way Humidification System
Using patented technology, the D’Addario Two-Way Humidification System features disposable, moisture-filled packets with a breathable membrane that provides two-way humidity control, meaning it can either release or absorb moisture to consistently maintain a predetermined relative humidity (RH) level of 45-50 percent.
Music Nomad Humilele Ukulele Humidifier
Music Nomad the leader in equipment care products, has developed an easy to use, no mess, and low maintenance Ukulele humidifier. The Humilele rests securely on top of the strings to safely and evenly hydrate your Ukulele to avoid these problems.
Final Notes on Humidity Control
To monitor the amount of humidity your instrument is receiving, we recommend the purchase of a digital hygrometer, a device that gauges and provides a read-out of humidity levels. It can be kept in the room where you store your instruments, or, better yet, in a central location inside the instrument case, preferably Velcro’d to the outside of the accessories compartment (facing the heel). The optimal range for your guitars and ukulele is 45-55% RH.
