I've just started using my Boss RC50 with my AxeFx. Everything works and sounds great except for this ground loop hum I'm getting. I know I could get an Ebtech this or that (which I just might end up doing) but what could the root of this problem be??
No noise until I plug my RC50 into the FX Loop:
AxeFX Output 2 --> RC50 Input
RC50 Output --> AxeFX Input 2
Most of the noise occurs whenever I connect the AxeFX Output 2 into the RC50 Input. Plugging the RC50 Out to the Axe Input 2 alone brings a little bit of barely audible noise but plugging in the Axe Out2 to the RC50 In alone brings the loudest noise. Both is worse.
The RC50's power adapter only has 2 prongs, no ground prong. I disconnected the Shield on one end of the cable connecting the Axe Out2 and the RC50 In and that made the RC50 freak out and overloaded its input (luckily I had my power amp turned down to zero). So I tried that cable to connect the RC50 Out to the AxeFx In2 and a regular cable to connect the Axe Out 2 and RC50 in. This definitely reduced the noise a bunch but it's still noticeable with my higher gain patches, especially if I'm not touching the guitar. Touching the jacks of the cables plugging into the RC50 makes it go away.
So what can I do here? I'm considering getting an Ebtech Hum X, but where in my setup would that go? I could also get the 2 channel Hum Eliminator, as I wouldn't mind if the tone going to/from the RC50 is altered a bit.
But before all that, how can I properly correct this problem? Is that even possible?
My rig:
Furman Power Conditioner
AxeFX Ultra:
- Output 1 L/R --> Carvin DCM3000L --> 2 1X12 cabs
- Output 2 --> RC50 In
- RC50 Out --> Input 2
All the rack units are mounted with shoulder washers on the front and rear of the units. There are 3 washers per screw on every unit: Shoulder washer for the screw head, shoulder washer on the front and rear of the hole (the kind that goes inside the screw hole).
Thanks guys!
