With increased power and newly added features, the Double Four Plus BG-80 is a worthy successor to PJB’s legendary BG-75 Double Four model. The BG-80 is a 90 Watt single channel bass combo with two four-inch speakers and a 3 band EQ that is perfectly tailored for bass guitar.

Other features include an auxiliary input for iPad/iPod, smart phone or drum machine, stereo headphone-out jack and a line out for recording. Recorded music sounds great through the Bluetooth function (V5.1 with aptX HD). In addition, the Double Four Plus is equipped with a DC input (USB Type-C port) connection which supports a mobile power bank of USB PD (Power Delivery) Protocol. This provides the ultimate in “Tone To Go” and busking possibilities, even where AC power isn’t available.

The BG-80 is ideal for all kinds of basses, and can handle the open B string on a 5- string bass with ease. PJB has applied its cutting-edge experience in designing small speakers to achieve a 4 inch driver with Swiss watch precision. PJB’s R&D facility utilizes the largest an-echoic chamber in the bass guitar amplifier industry as well as the transducer Klippel measurement system with laser technology. The result is PJB’s proprietary “long-thro” 4-inch speakers that have full frequency range up to the highest audio frequencies. Not only does this give greater clarity and transparency to the instrument, but also a high-fidelity sound to any backing track fed into the auxiliary input.

The cabinet is small and portable and built to the same high-quality standards of all PJB cabinets and can achieve a volume that is remarkably loud for its size.
