Eq effects loop

Hum in pedalboards is usually “ground loop hum.” You have two paths to ground, your audio ground and your power supply ground. You could use an expensive power supply with isolated grounds. But all you have to do is break one of the ground connections. You could disconnect the audio ground at one end of each of your patch cords. Or better, if you use one power supply, connect the hot and ground to only one of your pedals. Clip the ground wire on all the other pedal connections in your daisy chain. The power connections will then get their grounds through the audio grounds. No more hum
