KORG CM-400 WH - Clip-on Contact Microphone for Tuners (White)

KORG CM-400 WH - Clip-on Contact Microphone for Tuners (White)

The Korg CM-400 WH is a piezoelectric contact microphone that attaches to the instrument and transmits the vibration directly to the tuner, achieving more precise detection than the tuner's built-in microphone and avoiding interference from the environment. Its stable clip with internal rubber insert is designed to firmly attach to wind instrument bells , the scroll/nut of bowed instruments (violin, viola, etc.), or the headstock of guitars, basses, and ukuleles , without leaving marks or causing damage . The new 3.5mm mono mini connector ensures direct compatibility with current KORG tuners such as the TM-70T and other models with a mini-jack microphone input. The 1.5m cable with flexible jacket and slotted strain relief resists pulling and improves sound transmission during rehearsals, lessons, or performances.

Main features

• High-sensitivity piezo for precise vibration tuning, even in noisy environments or with large groups.
• Safe and gentle clamp : up to 30 mm opening with non-marking rubber interior that adapts to thin or curved surfaces.
• 3.5mm mono mini-jack connector designed for the TM-70T series and other tuners with mini-jack input.
• Robust 1.5m cable with soft sheath and grooved joint to minimize fatigue breakage.
• Ultra-light design : only 35g , ideal for carrying in the instrument case.
• White finish (also available in black, CM-400 BK).

Product benefits

• Reliable tuning in band, orchestra, or stage: captures the instrument's vibration and prevents "bleeding" from other sounds.
• Instrument protection : The rubber-lined clamp holds the instrument firmly without scratching or marking.
• Direct Connection : 3.5mm mini-jack ready for modern tuners; no adapters required.
• Ease of use : long, flexible cable to place it where the instrument responds best.

Use cases

• Brass and woodwind : Bell mount for stable reading during rehearsals and auditions.
• Bowed string : volute/tailpiece attachment to capture vibration with minimal transmission of ambient noise.
• Plucked string : Attach it to the headstock of guitars, basses, or ukuleles for precise tuning on the go.

Frequently Asked Questions

• Is it compatible with my tuner? Yes, as long as your tuner has a 3.5mm mini-jack microphone input (e.g., KORG TM-70T).
• Can it damage the instrument? No. The clamp has a rubber insert designed to prevent marks or damage when used correctly.
• What instruments is it suitable for? Wind (brass/woodwind), bowed strings, and plucked strings; also useful in educational and study contexts.
