The board as-is is really meant more for reverb, with a very short and fixed delay time. By cutting the trace, you remove the resistor by which the delay time is 'fixed' so that the potentiometer can provide a variable resistance, giving you control over delay time.
Leg one is disconnected. The second leg should be connected to ground, forgive my handwriting :D
