Why choose it

The SB21 combines the convenience of a clip-on design with the clarity of a true condenser capsule. Its cardioid pattern rejects off-axis noise, reducing feedback and bleed from nearby instruments. The rugged clamp and gooseneck hold firm even during energetic performances, and the battery option means you can use it with any mixer, even without phantom power.

Ideal use cases

• Live sound for saxophone, trumpet, trombone, and other brass
• Close-miking acoustic guitar, violin, and percussion
• Stage monitoring and in-ear setups
• Recording rehearsals or demos without a full studio

Good to know

The SB21 is built for the road: the preamplifier is compact and lightweight, and the included XLR cable connects directly to your existing stage snake or audio interface. For best results, position the capsule 5–10 cm from the sound source and engage the high-pass filter on your mixer if needed.
