When i first upgraded from a combo amp to a real rig i was introduced to speakon cables. The guitar shop i bought my GB shuttle 9 head at hooked me up with one and i plugged in and was ready to rock. I've since upgraded my entire rig again and am only now starting to read more about the different wiring configurations in with speakon cables. I've been hearing a lot of emphasis on the difference between the amp end and the cab end of the cable and am now concerned because I haven't been treating either end of the cable differently. The sound i've been getting is incredible, but i gig frequently and the speakon cable isn't labeled on either end, so i never discern one end from another when setting up the rig. Any thoughts?
