Hey all, Just got an MB Fusion from musician's friend, and super excited to try it but i don't have speakon cables. The manual says the speaker inputs are dual purpose 1/4", and Speakon inputs. But the holes in the center of the speakon ports are too small for a 1/4" cable! they just wont fit without me really forcing them in, and then they won't go all the way! Anyone else had this issue? Thanks!!
