Problem with ABY Splitter to External Amp (Ground Loop prob.)

[hotdropdieandcry]

Hey all.

I recieved my Morley ABY Splitter a few days ago and have been testing it for a while.
I tried to change powerstrips, cable rotations and so on, everything on the same circuit and off the same circuit.

Using Fender Bass, Morley ABY (Unpowered, due to leds only having effect from this), 2x Fender cables, Rocksmith USB Cable, Orange Crush, Grounded Powerstrip.

Current cabling goes like this:

Guitar to Morley In/Out -> Rocksmith USB to Morley A Input -> AMP to Morley B Input.

Setup works, but problems start when I connect my amp and the circuit makes a ground loop I guess?
The static noise is unbearable from every note I play. Syncing properly doesn't help ingame.
Switching to a 6string is even worse, the static becomes twice as annoying.


What can I do besides buying some expensive pedal which maybe doesn't fix all the problems?
I would love to get this to work properly. : (

You have a ground loop in your setup. I also have a Morley ABY, but I don't use it for this purpose precisely because it doesn't have a ground lift capability. I use my Morley so that I can connect two guitars to my equipment at one time, and switch between them.

Is everything in your setup plugged into the same powerstrip?

Yes, everything is plugged in to the same powerstrip.

I bought a passive DI box that I use just before the amp for this purpose. It contais a transformer that provides the isolatation and a switch so you can choose to isolate the ground. Its an Ultra-DI DI400P. The only thing to be aware is it has an XLR (3 pin microphone type) output, so you will probably need an adapter back to 1/4 jack to connect it to the amp.

This works quite well. However, there is one small issue with it being passive (doesn't require power), is that it results in a drop in the signal, so you have to turn your amp volume up higher.

The XLR output of a DI box is a balanced signal. It's not intended to be fed into an amp. It's intended to be fed into a mixer.

i got rid of a lot of noise buy sheilding and grounding my electronics cavity dont know that that matters since it was all done prior to useing the set up in rogue203 's set up guide. IT killed all the buzzing and noise from touching strings
