Hi! I'm from the Philippines and the gigging scenario is usually like this. Most of the time clubs here would have a decently powered guitar amp (50-100w) but not all clubs mike the amps so it can sit well in the mix with the vocals, drums, and bass. I use an HD500x.
To get more consistent sound both on stage and at the audience I was thinking of sending the PL outs to the onstage guitar amp's FX return, and the XLR outs to the PA. The problem I have though is that if I set up my patches with any of the cab sims on, the FOH sound may be good, but the stage sound from the amp would be usually muddy. If I set the output mode to Combo Power amp, I know I would get a good sound on stage but I fear that I would have that harsh DI no cab sim sound coming out of the PA.
So I guess my questions boil down to the following:
1. Do the XLR outs have some sort of "always on" compensation / speaker sim even if the active patch has the cab sim turned off?
2. If not, then I would have to turn on cab sim so that the HD500x's XLR PA feed would sound right, correct? How do I now make the stage amp sound good in this set up since the cab sim already colors the sound?
Thank you
MH
