A music piano keyboard (yamaha) I have provide a headphone out that sound terrible (it hum at high volumes) if we connect to a guitar amplifier. Using the attach simple circuit I was able to connect to the amp. It sound better, but it still have a hum sound. It is more of a digital/clock sound , high pitch. What change to the circuit is necessary to eliminate the hum noise.
