The Bottle, Blue's highest achievement in quality and innovation, is their flagship recording tool, combining low noise and superb transient response integrated with a system of eight optional interchangeable capsules (the Bottle Caps). In an instant, these bayonet-mount capsules can be exchanged to provide different tonal characteristics and pickup patterns while the 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. When combined with the versatility of the Bottle Caps, the Bottle provides the ultimate recording experience. In keeping with our philosophy of sonic purity and fidelity, we do not incorporate pads or filters into the Bottle. Rather, we believe that proper mic selection and placement eliminate the need for such extraneous circuits which only degrade signal integrity.
