KORG CM-300-BKRD - Piezo Clip-On Microphone for Tuners (Black/Red)

KORG CM-300-BKRD - Piezo Clip-On Microphone for Tuners (Black/Red)

The Korg CM-300-BKRD is a contact microphone designed to send the instrument's vibrations directly to the tuner, guaranteeing stable detection even in noisy environments (band, orchestra, rehearsals). Its rubber-wrapped clip attaches securely and gently to the bell of wind instruments , the bridge of violin/viola/cello , or the headstock of guitars and ukuleles . The cable has been redesigned to offer greater flexibility and durability where it connects to the clip, improving signal transmission.

With a maximum opening of 30 mm , a 1.5 m cable , and a 6.3 mm mono jack connector, the CM-300 provides direct compatibility with Korg tuners equipped with a microphone input. The black/red finish adds visibility and aesthetics without compromising discretion on stage or in the classroom.

• How do I connect it? Directly to the tuner's 6.3 mm jack input.
