I got a RF 1000BD, the person who sold me the amp gave me this bass knob but with no cord. so i bought the cord at Walmart, it was just an ordinary phone cord. i hooked it up and everything, the bass knob didnt work. so my question is, wrong knob or might be the cord? i was thinking i might need some kind of special cord from the actual company. thanks.
here are the pics of the knob:
