Multipurpose B8 capsule for instrument and vocal recording, and the ethereal "being there" sound of the B4 omni for ambient room and drums.

The Blue Bottle Rocket Stage Two is an innovative and unique vacuum-tube microphone system for virtually any recording need. The Blue Stage Two combines low noise and superb transient response with a choice of 9 different interchangeable capsules—the Bottle Caps. In an instant, change these bayonet-mount mic capsules for a stunning variety of tonal characteristics and pickup patterns without shutting off the power. Get all of the capsules, and it's like having an entire Blue microphone locker in a single system.

Precision-shaped and hand-assembled, the Bottle Rocket Stage Two is crafted for a lifetime of use. Its transformerless Class A discrete amplifier circuit is a thoroughly modern design with a nod to the classic circuits of yesteryear. With the Blue Stage Two mic's single hand-selected ECC88 vacuum tube, you'll hear musical detail and subtlety previously heard only in microphones costing thousands more. The Bottle Rocket Stage Two includes a custom-built flight case, a high-definition tube mic cable, and a shockmount. You also get the innovative Powerstream power supply, which not only ensures ultra-stable performance but also features a soft-start feature that maximizes tube life and minimizes startup time.

Capsules designed for any mission
Both the Stage One and Stage Two Bottle Rockets can take advantage of the Bottle Caps, Blue's family of 9 interchangeable capsules with different tonal characteristics and pickup patterns. Each Bottle Cap is designed to provide the recordist with the ultimate sonic solution for their respective application. Get them all and you'll have an entire Blue mic cabinet at your fingertips. This Stage Two bundle comes with the B8 All-Purpose "TPO—The Popular Opinion" Bottle Cap and the B4 Omni Mouse.

B4 Omni Mouse: Perspex Sphere Pressure Omni Small Diaphragm: "The Big Omni"
The Blue B4 evokes an ethereal quality sought after by producers and engineers alike. The Perspex sphere which houses our small diaphragm capsule, hand-built by Blue engineers, is a unique design made popular in the 1950s on the RCA Red Seal series recordings. For room sounds and ambient drum recording, nothing parallels the sound of this capsule.
