I hear you. My back does too. A modelling preamp pretty much demands an FRFR, anything else does not really make logical sense. I just still wonder if the POD/FRFR combination is a convincing replacement for a tube amp. I am not religious about this. I had Spider Valve MKII's, then I had Digitech RP1000 running into an Engl Screamer, and I tried the RP1000 straight into the PA as well. I used a Tech21 FlyRig 5 into the PA. But today I have a Hughes & Kettner Grandmeister 36 head that I can carry with one hand. It has 128 presets and 4 built in channels. A basic set of effects. Nothing as grand as a Pod or Helix. But it sounds like a tube amp cause it is. But still, ff there was a Firehawk 750 weighing half as much, I would give it a try with a Pod HD!
