Add even more meat to the sound of your bass cub! This is a powered speaker that adds an extra 100 watts, making a beautiful little stack with plenty of headroom for small gigs. Excellent condition. Most of my gigs require bigger rigs these days, so I'm just keeping my Bass Cub for practice and parting with the extension speaker. Info from PBJ: The PB100 powered cabinet is a perfect complement to the Phil Jones Bass Cub, adding that extra punch and low end. It has the exact physical size as the BG-100, so together they form a powerful 200W mini stack. I'll sell it for $240 shipped conus. I can't think of any trades off the top of my head, but feel free to PM me with any offers. Thanks!
