I've been gigging the Orange Bass Terror this year and it's great fun. I can only echo what has already been said. Plenty of old school thump. I think it's got a kind of punk rock spirit, no thrills controls, just plug in and play. It does reggae well, it does country and of course it does rock. What's not to like? I'm taking mine out with the SP210 cab and it's awesome.
All that said if you tried the Little Bastard and loved it, you could always play it safe.
