I built a 6g15 Stand alone re-verb unit, it works well with my 5E3 no hum at low volume or high volume when the amp and verb are about 12 to 18 inches apart. At a recent gig there was no room to place the the verb and amp separate therefore I placed the amp directly on top of the verb where a vibration or seems like a hum developed between the 2 units. It is OK at low volumes but at around 3 to 5 that's when it becomes troubling. It sounds like a 60 cycle hum somewhat. I did not use any shielded wires in the build I need to address this as we are scheduled to gig at the same place in a few weeks. Any suggestions???
