I'm still pretty new to Helix. When I first got it, I went 4CM into the FX loop of my Bogner Atma. Sounded fantastic on stage, but I was never really happy with the FOH tone. So I bit the FRFR bullet and now go XLR out into the PA, and digital out to a Line 6 L2m as floor monitor. I now hear exactly what the audience is hearing. The L2m is beefy enough that I don't really miss the 'real' amp.
