I have a question pertaining to combining heads and cabs of different makes. Specifically, I have my eye on an Eden 410XLT and/or a SWR Goliath III, and either an SWR 4004 Workingman's Head, a SWR 500X Head, or an Eden WT-400. I was wondering if anyone had either reassurances or horror stories about the consequences of using a rig made up of components of multiple brands, or about the individual products themselves. I know about impedance matching and things of that nature; I'm more concerned about certain cabs not being able to handle the output of certain heads. Any advice from more experienced comrades would be much appreciated.
