A small PA cab slid into the back of my Rumble 200 and BARELY nicked the extension speaker jack. From 5ft you can't even tell it's been touched. Well, that Rumble 200 is now a paperweight. That tiny blow that didn't even cause any cosmetic damage, cracked the freaking board rendering it totally DOA. My tech said the stuff in there is such low quality mass stamped crap, he is surprised any of them work for more than a few months. I know many have had them last years, and I had no other issues, but I am not making this up. A ding to the extension speaker jack rendered the combo land fill. Sob story over, my mission begins today. I'm going to reload it with a Kappalite 3015, remove the now-worthless electric guts, and use the bracket from a Genz-Benz Shuttle combo to attach a Shuttle 6.0 to the top, creating the first 33lb 15 combo that is 300w and can handle an 8ohm extension speaker for 600w. I know this will take some cab tuning that is beyond my math skills, but I have a good friend that is going to do the removal for me who will do all that measurin' and cipherin'. Thoughts? Suggestions? Don't do its? Other speaker suggestions? Who wants one?
