COMPACT PLUS BG-450.

Powerful Small Combo.

The Compact Plus BG-450 is the pinnacle of PJBs line of small and light weight powerful compact bass combos. It is the same size as PJBs C-4 speaker enclosure with a power amplifier that will reach up to 500 Watts with four internal 5 drivers.

The BG-450 contains the latest proprietary PJB chrome dome drivers which are the most efficient five-inch speakers ever engineered by PJB. The result is a perfect pairing of power and driver efficiency that makes it the best sounding 45 combo ever made by PJB and, remarkably, with less weight. It has an incredible punchy sound that cuts through air as a knife through butter with a solid and powerful low-end response normally associated with a much larger combo.

In the heart of this amp lies a formidable ultra-high-energy power supply using a Class D power amplifier for high efficiency which equals less heat and less weight, and is coupled with a pure Class-A, ultra-low noise pre amp. This combination completes a power section that achieves a massive dynamic range that allows the player to attain the best tone in any playing situation.

The pre-amp design includes a single channel equipped with a variable gain input section that matches precisely with both active and passive basses. It also features a mute switch and the classic PJB 5-band precision EQ system that achieves the broadest range in tones imaginable with just 5 controls. This allows the player to effortlessly locate their perfect tone within seconds.

The send /return FX patch can be blended to the direct signal allowing even more tonal opportunities. A secondary AUX input allows for practicing along with backing tracks via a 1/8 stereo jack. Back panel features include a Line Output jack that allows the BG-450 to be used in slave mode coupled with one or multiple amps, and a line input that provides the ability for an external pre-amp to be connected if desired.

The DI balanced out can be pre or post EQ and offers a ground lift to avoid problematic hum. Speaker output is via a Speakon NL4 socket perfectly matched to run a C4 or C8 cabinet. The amp can run on any AC voltage from 100 volts to 240 volts.

The Compact Plus puts out a punchy 300 watts into its own speakers and up to 500 watts when connected to an external cabinet. The BG-450 at max power will cover a wide variety of playing situations. For environments that demand much higher volume PJB recommends a BP-800 amp with PJB cabinets, or a BG-800 Roadcase as powerful alternatives.
