Anyone using a GK or other system and know where I can get a 4 pin speakon cable? Apparently GK used to ship a cable with the amp as well as the speaker but now they've stopped. Dan Elliot, you scurvy dog! So I need to get a 4 pin speakon to use their biamp system, and I don't want to modify my cab until I have the cable in hand. I feel pretty sure I can make one if I can get the connectors and the wire.
