The Compact Plus BG-450 is the pinnacle of PJB’s line of small and light weight powerful compact bass combos.   It is the same size as PJB’s 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 4×5 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
