I use CMC-8's > SP-SPSB-1 and 3 > Jukebox 3, and i really love the mini sp-spsb-3 bat box, with the tiny ass batteries. If the sp-spsb-2 is anything like the -3, then you shouldnt have any problems whatsoever. One of the 2 times i got busted, someone got my sp-spsb-1, not my jukebox, so i try not to use my -1 if at all possible, but i did get it with the preamp setting.
