Yeah I heard that too... about his illness.. I have not played any of the basses but I would love to get one.. The Lil G I have is an older one I thing with that handle/tilt stand.. That is the only thing I don't like about it but that is so minor.. The cab is great.
Late response, but I talked to Sammie about two weeks ago....he has revamped the Lil G speaker line. He's added two 5" mid drivers and offers a cab with a built in 1400w power amp, which is pretty crazy. All you'll need is a preamp of some sort and you're set. The cabs are a little bit bigger though, and I imagine the weight has increased by 10lb or so, but I expect that they still sound great. The cabs are greatly improved with Tolex covering and corner wheels built into the cab. I'll be checking one out in the next week or so.
You also may wanna check out Boom Bass Cabinets too, also made by a local guy in MD. Similar style, great tone, and lightweight....he makes a 12"x15" that I'm really interested in.
