I've been ampless for a couple months now and it's been killing me. I've been working at a temp service for a little over a month now and have exactly $500 saved up. I could probably get the rest of the money off my parents for the 400RB. I haven't worked in a week and don't know when I'll work again. I was originally saving up for the 1001RB 210 combo which costs about a grand. It just seems like a better value than the 400RB 210 combo. How useful is the bi-amp feature (the 400RB lacks it)? Does the 400rb combo basically have an SBX cab? Is it sealed? I'm not in a band right now and the amp will basically just be a bedroom amp, atleast for now. Do you think I should wait for the 1001RB or just get 400RB right now???????
