Digi002 outputs and reamping

[Wade]

I've searched and searched for an answer to my problem. I have a 002 and I'm wanting to use my reamp box to reamp guitar tracks. I am coming out of the 002 output into my reamp box (real reamp box with ground lift and volume knob to adjust how hot the signal is, not a DI used backwards) into my pedalboard and then into my amp. The cable coming from the 002 to the reamp is a balanced TRS to Male XLR and then I'm using high quality guitar cables (mogami) to the pedalboard and/or amp.

No matter which output I use on the 002, I'm getting a terrible hum. It's even noticeable when the guitar track is playing. So the output is working, but there is a ton of noise. Both of my amps (Marshall SL5, Marshall JCM800).

The humming is noticeable when there isn't even a track playing. If I yank the cable from the 002, the amp is silent. I've triple checked my outputs, I only have 1 track going out to the amp and I have it solo'ed so that my mic doesn't pick up my montiors playing it back. I've even dropped the level of the send in Pro Tools way down to see if that might have been the issue.

All my DI tracks recorded with a DI and a preamp (not the onboard ones in the 002).

Any help would be greatly appreciated. Thanks
