Bad Sound with Amp Out Source set to Pre Cab/IR and Pod Go Cab disabled

I came across this strange phenomenon when trying to figure the best way to connect and use my Pod Go with an external amplifier. I would like an explanation as to why the sound changes when I turn on-off the Pod Go Cab block?  Here is my setup:

  • Global Settings, Amp Out Source set to PreCab/IR since the amp has a speaker cabinet.
  • Amp Out connected to the external amp Return to bypass the amp's preamp stage.
  • Pod Go Cab block moved to far right in the chain since Amp Out Source is set to PreCab/IR.
  • Main Out set to Line and Left/Mono connected to monitor speakers for comparing modelling tones.

 

With the Pod Go Cab block set to 'On', the tone from the external amp is what I expect and sounds about the same as the monitor speakers.  But when the Pod Go Cab block is turned 'Off' the sound is completely different (distorted and unpleasant) from the external amp.  

 

If the the Pod Go Cab is bypassed by setting the Amp Out Source to PreCab/IR, why does turning on-off the Cab block change the sound?  I would expect there to be no change in the sound since the Cab block is (supposedly) bypassed in the Global settings.

I tried reproducing this with my setup, but I'm not seeing it. The only way I could get the cabinet on/off state to have any change in sound through my external amp was if I set the Amp Out Source to Main Out instead of PreCab/IR. When I have Amp Out Source set to PreCab/IR, turning the cabinet block on and off did not change the sound coming out of my amp at all.

I know these are probably dumb questions, but are you sure you're using the Amp Out jack for the cable between the POD and your amp? If that is setup correctly, then are you turning off your monitor speakers so you only hear what's coming out of your amp?

The weirdest thing.  The next day I didn't have that problem, or at least on other presets. I didn't make any changes from the previous day and wondering if it was one particular preset or just needing to be reset? <rhetorical>  As my dad use to say; "You're not holding your mouth right!" I'll go back and search.  

 

Indy, appreciate the response!
