Clip-on Contact Microphone for Tuners

The LORDWORLD CM400 is a piezoelectric contact microphone that clips directly onto an instrument for accurate tuning. A 3.5 mm mini-plug connects to compatible tuner bodies, and a five-foot cable with a soft sheath resists disconnection. At 35 g it adds negligible weight to the headstock.

Suited for noisy rehearsals, not wireless setups

Musicians who tune in loud group environments will benefit from vibration-based sensing that ignores ambient sound. The 30 mm maximum clip width fits guitars, violins, ukuleles and similar instruments without damage. Players needing a built-in display or wireless transmitter should consider a dedicated clip-on tuner instead.

3.5 mm mini-plug and 30 mm clip width

The 3.5 mm connector determines which tuners accept this microphone, while the 30 mm clip opening decides whether it fits a specific headstock or bridge. Verify both measurements against the target instrument and tuner before purchase.

Questions about this item

Which version of the CM400 should I pick for my instrument?

The CM400 comes in black or white; both share the same 30 mm maximum clip width, 5 ft cable, and 3.5 mm mini-plug, so choose the colour that matches your gear.

What does the piezoelectric pickup actually do on stage?

It senses vibrations directly from the instrument body, letting you tune accurately even when other players are making noise around you.

What does the 3.5 mm mini-plug connect to and what limits it?

The 3.5 mm plug goes straight into a compatible tuner input; the 5 ft cable length sets the maximum distance between your instrument and the tuner.
