I was given two San Franciso Rush The Rock cabs, been piecing together parts (main PCBs) to put them back together, poking around the wiring, on one of the cabs I noticed an odd switch placed in between the auxilary wiring that runs from the main PCB to the sound board, it's like a 4 position rotating dial (light?) switch. First pic is the cab without it and the second pic is the cab with it. What was the purpose of this mod? Any reason I can't undo it without worry?
