The CM-400 is a clip-type contact microphone using piezoelectric elements that transmits vibrations directly to the tuner by attaching the microphone to your instrument. The CM-400 enables even more accurate tuning than the microphone on the tuner itself, and allows the instrument to detect its own sound more reliably, especially when practicing with a large group or in other environments where the sound is easily affected by surrounding sounds.
Durable, Disconnection-Resistant Cable
The cable, which excels in efficient sound transmission, is made of a material with a soft and flexible wire sheath. The slit shape of the joint between the clip and the cable reduces the load on the wire and makes it difficult for the cable to break.
Changed to a more stable mini-plug
The output terminal for connection to the tuner body has a new mini-plug, which works well with the TM-70T and ensures stable tuning.
Clip section for stable attachment to various instruments
The maximum width of the clip is 30mm, and the inner rubber part is designed to be attached to any instrument without leaving any mark or causing any damage. It can be attached easily and securely to a variety of instruments, such as the bells on wind instrument, the heads of bowed string instruments (such as a violin), guitar, bass and ukulele heads, and more.
- Plug: 3.5 mm monaural Mini Plug
- Maximum width of clip: 30 mm / 1.2”
- Cable: 1.5 m / 5’
- Weight: 35 g / 1.23 oz.
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.
