Before reading the following, keep in mind that I until today to exchange any equipment if I have to!!! Thanks. ========= Hello, I think you can help me out. I am a fairly bright guy, but I'm also fairly confused. I am used to combo amps that take care of all this ohm/watt math stuff I now am a proud owner of an Ampeg B2R head http://ampeg.com/products.htm?product=12&catid=14 running to an Eden D212 XLT cab (4 ohm version) http://www.eden-electronics.com/212XLT.html that sounded great in the shop and at the first gig I played with it. The next two shows left me confused. After reading your article I think it may have something to do with the cable from the head to the speakers. I thought nothing had changed in my setup, but the article reminded me that I did change that cable. My sound went from a tight, full, bass player's dream of a tone to a fluttery fart noise that I am ashamed of. There is some of the good sound in there, but it is covered by a fart. Could it be due to the cable or is something else taunting me? I've tried fooling around with all the settings and got nowhere. Should I return the Eden and get the best matching Ampeg cab? May a 4x10 setup? Which one is the best match for the B2R? Thanks for any suggestions! Take care, -E.
