I saw that you run power ac cables down the expando tubing with guitar lines like on Pete Thorns nova system rig is there anything special your doing not to get hum in the lines? Special cable or wrapping it in anything?
Well it is never perfect and I try not to do it. But the absolute best way is to make the lines balanced to the pedal board and back. this can be done with some passive radial dual di's. This will get rid of all the noise period. Dave
