The BG-80 is a Professional Miniature Practice Bass Amp
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 90Watt 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.
To get the ultimate bass sound from a small speaker cabinet, PJB has applied its cutting-edge experience in designing small speakers to achieve a 4 inch driver with Swiss watch precision. Using our extensive R&D facility which includes the largest an-echoic chamber in the bass guitar amplifier industry and the transducer Klippel measurement system with laser technology, PJB was able to develop the proprietary PJB “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 your 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. What you hear from the Double Four Plus is the closest you can get to how your instrument actually sounds, and, is remarkably loud for its size. This latest model in the Double Four series is a remarkable achievement in design, features, and tone.
