I know nothing about piano but recently got one (Yamaha PF1500). It came with a stand with two pedal. According to the owner's manual, the sustain and soft pedals are connected to the left and right ports respectively.
But the cables are concealed inside the stand. When they come out, I have no way to tell which one is which. All I see that one jack is grey (left one) and the other is black in color.
Could anyone help me to figure out which one is which? Thanks.
