Re: Hum trouble with 6G15 Reverb kit
This problem has been around a while, Howard. I went through it too and got some help here.  
 
What's probably happening is that the use of a 3-wire cord with both the amp and the reverb unit sets up a ground loop from each power cord ground and the grounded shield of the patch cord running between them.  
 
I can't remember if the fix was to use isolated jacks and not to ground anything inside the reverb unit to chassis except the green cord wire or to star everything to one common point only. Maybe someone will chime in and repeat the advice.  
 
Me, I was feeling lazy so I just disconnected the green ground wire inside the unit. The protection of the ground on the amp follows the patch and guitar cords to the guitar anyway.
