I just sold a proper working and sounding BBC 212 "The Tank" cabinet to a gentleman through a Craig's List ad. It was a parking lot sale, he did not try it out, he did his homework and knew what these were all about. He gets back in touch with me after getting it to his home and tried it out. He says it rattles at certain frequencies and will break up hitting certain notes. He did A/B comparisons with other cabinets and amp heads and the BBC is not holding up the the others. I have been using this cabinet for months at a weekly gig (Fender Rumble 500 head) with no issues. The last gig was a week ago. I bought this cabinet used on Reverb.com months ago. I have another BBC 112 that suites me better. He said he will try it out at a band rehearsal tonight and let me know how it did. If he doesn't like it he said we will "have a conversation". The BBC line is not for everyone. A friend of mine bought a 1015 and returned it. I don't mean to be harsh saying "Buyer Beware" but that is the way I feel. I'm not feeling the return if that "conversation" goes that way. Is that bad etiquette?
