Rookie question, but I'm setting up a new rig that is going to consist of a Mesa D800+ head and a pre-Fender SWR Goliath Sr. 6 x 10 cabinet. The Mesa head has Speakon connectors, but the SWR cab only has the old 1/4 inch input. I need to get a cable for this set up and was wondering if anyone has a good recommendation for one that will work. Many thanks.
