From Modern To Vintage.
And Back Again.

Bottle and Bottle Rocket Stage One are at the heart of the Interchangeable Capsule Series, offering unparalleled sound quality and performance. The flagship Bottle Class A tube microphone features a warm and modern circuit that delivers soulful response and larger-than-life reproduction. The Bottle Rocket Stage One FET condenser delivers exceptional sonic clarity to capture the nuance of any performance. Both mics are compatible with Blue’s interchangeable Bottle Caps mic capsules, so you can build a custom microphone platform tailored to your creative style.

Mic Capsules with Character

The Bottle Cap Series offers an unprecedented creative palette for Bottle and Bottle Rocket Stage One mics.

The series delivers an extraordinary variety of timbres and polar patterns—with options ranging from vintage to modern—forming a world-class collection that would cost tens of thousands of dollars to obtain with individual mics. Capture the unique soul of your voice or instrument—without resorting to “fixing it in the mix” with plug-ins.
