Replacement for contact microphone on guitar tuner
This item was purchased to replace one that had stopped working. It worked well and was good value for money.

KORG CM-300-BK contact Microphone for tuners
The KORG CM-300-BK contact Microphone for musical instrument electronic tuners is very well made, works well with the tuners I have tried (Korg, Seiko and Boss) without picking up surrounding noise, Good price and delivered quickly.

Contact mic I haven’t used once for it’s intended purpose
Clamps on to unusual things and allows for the recording of the strangest of sounds. I think it’s supposed to be used for recording saxophones. I have used it mostly to record vibration based sound effects. I have flung it at objects to record impacts. It’s really durable and really affordable. I don’t know if it sounds good for recording sax, it sounds great crashing into pillows and being dragged along towels.

Does the job
Great idea for a simple add on to (for me an acoustic guitar) musical instrument. On the guitar the clip and cable gets in the way a little and you have to have a good amp to hear the guitar on.

Good for instruments with no built in pickup or pre amp
Works fine but some interference from the TM60's built in mic. I will use this for my accoustic guitar but continue using a 1 meter patch cable with my electric's and electric accoustic's because I get a much cleaner signal.

Works very well
It works well with my 20 year old tuning device! I can now tune my instrument even with background noise.

Even though a "tuning mic," works like other contact mics and did a good job picking up sounds of vibrating metal set structures in a theater application (sent wirelessly through transmitter set to instrument level). Very robust construction compared to other cheaply assembled similar products. Good value!
