Hi - A quick question for Amsdenj or JLondon. First thanks for your in depth replies. Just for clarification, 1) Are most presets when purchased from marketplace or some downloaded from custom tone created with headphones or studio monitors which I think are FRFR? 2) If so, if I tweak my presets the way I want them with the PC at home on FRFR (amps and cabs on helix), will the audience then hear what I hear from the PC if I run XLR from power cab to FOH PA? Also, I'm still confused by the PC XLR output on the other modes. - (speaker model and speaker model/natural) If I like one of those (with the cab eliminated in Helix chain), and then use PC XLR output to FOH from those modes, will the audience hear what I hear from the PC? Thanks again!!
