I specificly did not go to a di for several reasons

2 I have never meet any guitarist who desires the dry harsh sound of thier
electric guitar plugged straight into a mixer

right now it's pretty much the only way I can play the electric because the noise gets so tiresome so quickly

the fact that the ground lift isn't connect to the through signal does seemingly eliminate a DI box as a fix.

I am assuming electric guitar as the amps you mentioned do not really do
justise to a acoustic guitar


yes it's a Nashville telecaster

I am guessing you have a single coil pu system  these tend to amplify hums
there is a reason twin coil systems are called "humbuckers"

the guitar has three single coil pickups but the hum is there when the guitar isn't even plugged in so it can't be the guitar. All I have to do is plug in a cable. That's why I suspect RFI. There is no hum when the amp is plugged in and turned on with nothing connected. The hum starts as soon as I plug a cable into the input. The hum is the same whether I plug the other end of the cable into a guitar or not.
