I was going to buy the JB-2, but after seeing and playing the Sterling MM Ray34 I was swayed. The JB-2 sounded weak and overall flat, but the Ray deep bass and bright highs. It was about 30-40% louder, too. I tried out a Lakland 44-01, L-2000, SB-2 and a Stu Hamm Washburn (dreaming). The sterling won out though.
