KORGCM100L Clip-On Contact microphone For Tuners

I bought this product to experiment with the recording of sounds of vibrating objects and it works like a charm (much better than the other, relatively more expensive contact mics I have been trying). You can clip it to your desk or your lamp or a pot, etc and may hear sounds you have never heard before. If you are into electronic filtering and processing, you can do lots and lots of things to those sounds of course.It looks like most people here have bought it for use with tuners. I tried that too with an old Korg AT-12 and an accoustic guitar and the result was great.I connected the guitar to an amp (Roland Micro Cube) and the mic's pickup power is perfect but what it hears and transmits is the vibrations of the wood of course (not the events in the resonance chamber), and this is a matter of taste and purpose, some may like it, some may not. I attached it to an harmonica, again, the pickup was very powerful and clean.Attention: contact mics have significant impedance and gain requirements. That is, if you get this mic and connect it directly to your laptop or handheld recorder, etc, it will not work. It requires interfaces but nothing fancy. In my case, it works great with the guitar amp mentioned above (Roland Micro Cube). I also have an M-Audio Firewire Solo interface and connecting the mic to its guitar input to record with Logic Pro software worked perfectly well. I also tried putting a simple 4-channel mixer in between and the result of that was fine too.In short, this mic is a superb product and it is only 10 dollars!

I play trumpet and ordered this product so I could tune my instrument more accurately during both my own practice time and the general tuning note while playing with my symphony.The idea behind a contact microphone is simple: it measures the vibrational frequency of the surface it's attached to and displays that on the face of the tuner. This means that it'll only pick up one set of vibrations and won't react to any vibrations it's not physically in contact with. Perfect for a symphony setting where you have 100+ musicians around you playing at the same time.It works flawlessly with all my trumpets (and my acoustic guitar, for that matter). I use it in conjunction with my Korg Metronome/Tuner (which I love, by the way).It's as easy as plugging it into the port on your tuner (make sure it has a correctly sized port!) and clipping the microphone itself onto your instrument. Then tune away, and enjoy incredibly accurate readings with no interference from other sound sources!

The clip on tuner mic works great. It very useful for tuning around other people playing or warming up to be sure you are tuning your instrument, especially for beginners.It can also be used to monitor your own playing within an ensemble to be sure you are maintaining your intonation under normal playing conditions. I would recommend this as a spot check only, particularly if you are getting feedback about your intonation from other players or the conductor. You can also use it in practice to verify the minor tuning adjustments unique to your instrument.That said, you must develop your ear and learn to hear what is and is not in tune, and to hear yourself amongst an ensemble. It does you no good to play a perfectly piched note, if the ensemble you are in is not perfectly in tune. Tuning individually is absolute, but in an ensemble, it is relative.

I teach guitar classes at a community college and spend my days in a room full of twangin' 'n strummin' guitars. Human ears and tuners with external mics, including iPhone app tuners, have trouble in such an environment. Why? The cacophony of competing pitches befuddle both brains and tuning machines. So I bring an extra beefy Seiko Sat800 Durable Style Chromatic Tuner and Korg CM-100L mic to class for students to use. And it works great: clip to the headstock and it isolates their guitar from the din and delivers a clean signal to the Seiko.The Seiko tuner has hit the deck many times and still looks like new after a couple years. Unfortunately the CM-100L is not nearly as durable: wires are thin, delicate and prone to breaking. If I was the only one using the CM-100L, it would probably last for many years. But students are rough and can't stop themselves from tightly wrapping the wire around the tuner after they're finished (although I ask them not to). The wire gets stressed at the mic clip and/or plug and shorts out. I burn through one or two CM-100L per semester. I found a big gob of silicon sealant on stress points helps extend the life of the wire (electrical tape is useless).Great product: easy to use and makes tuning in a room full of guitars a snap. Wish they made an industrial strength model with big beefy cables...

I bought this product 4 years ago and it still works flawlessly: it's simply a device that you connect through its 1/4 jack to another device (a tuner, most of the times) and you clip the other end to your instrument. I've never had any problem with it and it works perfectly to tune my guitars, cello and violin (I have not tried other instruments). I even connected my acoustic guitar to my amplifier with this device and it surely DIDN'T sound pretty but you could clearly hear every sound and every pitch played in my instrument and I just had a little fun doing it.It is fragile thou, so you better not use it to tie your pet with it.
