I have found that I need look no further than the PJB line of amplifiers to define and find my sound. I recently purchased the new Double Four BG-75 in red. It is everything I had hoped for in micro bass amp. Super light weight and easy to use. The low end bass is huge. With plenty of volume for a small space it is perfect for accompanying acoustic instruments. I have also used it with amplified guitar and a quiet drummer. The Double Four keeps up just fine. We ran an acoustic bass through the Double Four with no problem. The amp is so small it really should come with a protective cary case. *I also own a PJB Super Flightcase BG-300 for bigger situations. The Double Four BG-75 is one solid piece of equipment you will be happy to own. Bravo AAA+++
