Hey all, I got a WT-550 last night and I want to try it out. Right now I've got a Markbass 210 combo and I use an Eden 210 XST as an extension cab. I am probably in the market for a 210 XLT but until then, can I run the 550 through the MB 210 and the XST? I know how to disconnect the MB 210 speaker from the LMII head--do I just need a 1/4" to run from the new head into the MB 210 speaker while running another connection from the head to the XST? Any ideas would be greatly appreciated. Thanks!
