Beautiful and rare early-production Blue Bottle tube condenser microphone system. This is unit #404—built by hand in Latvia during the company’s most desirable era. It’s one of the most sought-after versions, and it’s been kept in pristine, like-new condition.

This early mic locker set includes three highly desirable Bottle Cap capsules:

Included Capsules:

• B4

• B6

• B8

Includes the original rugged Blue flight case, champagne 7-pin cable, and power supply.

Known for its stunning sound and unmatched flexibility, this microphone is a true studio workhorse. No longer in production and increasingly hard to find, especially in this condition. It’s a top-tier choice for collectors and professionals alike, and only going up in value.

NOTE: I also have it cross posted locally on other platforms. Its availability can change. The listing will remain active accordingly.
