The Bottle is Blue's flagship recording tool and its highest achievement in quality and innovation. The Bottle combines low noise and superb transient response integrated with a system of interchangeable capsules, the Bottle Caps. In an instant, the bayonet-mounted Bottle Caps can be exchanged to provide different tonal characteristics and pickup patterns while the included power supply remains on. The Class A discrete amplifier circuit of the Bottle is a thoroughly modern homage to the past, with a design utilizing a single hand-selected EF86 pentode vacuum tube in triode mode. The Bottle is the definition of craftsmanship, with hand-assembled custom components found throughout. With eight different Bottle Caps to choose from, the Bottle provides the ultimate recording experience for any application.
