Just unpacked this thing! I haven't had much time with it, and I used my Rumble 350 head, but at first blush, this thing is tight and punchy! I'm going to use my RH750 tomorrow for band practice for a different comparision. I think this thing is going to be cool, but I'll post my findings tomorrow after my practice. This cab has several nice features like a diamondplate kickplate, nice built in wheels and handles at the top of the cab for pretty easy manueverability. The best by far, however...it weighs 77 lbs.! I have the Super Bassman 300 watt tube head on its way as well, so I may very well be on my way to bass nirvana!
