FX Loop Stereo signal to a second amp

[arbonino]

Hi, I have a technical issue regarding a certain setup with the POD Go.  I have two amps: a Marshall JVM410 combo and a BOSS Katana Artist. I want to use the distortion of the Marshall, with the Katana mirroring what the Marshall is outputing, that is, using the Katana as a power amp. The reason behind using two amps is that I want to use time-based stereo effects on both amps. 

The stereo effects work with no problem as expected, but the problem is that the Katana doesn't "mirror" the signal from the Marshall. Instead, the sound comes clean through the Katana, while using the distortion on the Marshall.

 

This is how I set it up:

- Guitar to Guitar in of the POD Go.

- POD Go Send to Marshall front Input.

- Marshall Send to POD Go Return

- POD Go L Main out to Marshall Return.

- POD Go R Main out to Katana Return/Power amp inputs.

 

In the POD Go preset:

- I have the FX Loop Stereo block turned on.

- I turned off Amp and Cab.

 

Using the POD Go R Main out to the Katana Return produces the clean sound (no distortion), without outputing the FX Loop signal passed through the Marshall amp. Using the POD Go R Main out to the Katana Power amp input produces no sound at all.

 

I don't know if I am doing something wrong. Is there something like a global setting which I have to turn on to output the signal passed and returning from the FX loop to another amp? Is it possible, or I am not understanding correctly how FX loop works? I appreciate your help.
