The Neumann MC 4 is a clamp for attaching the capsule and gooseneck of the Miniature Clip Mic System to the frame of a double bass and similar instruments. The self-adjusting spring mechanism and rubber coating ensure reliable attachment without risk of damage to the instrument.

The gooseneck mount rotates for variable alignment and locks securely in 45° increments. The included reducer can be used to adapt the clamp to particularly narrow instruments.
