Thanks, I got it figured out. For those who need assistance in the future, I'll enumerate my connections:
1) Guitar plugs into the Trio guitar in port.
2) Amp port of Trio to Guitar in of POD.
3) Mixer port of Trio to FX Return L/Mono of POD.
4) Add an FX Loop to your patch. Put it in channel B (or after the amp), but before the mixer.
5) Add a reverb in Channel B after the FX loop for some ambiance.
I'm sure there are other ways, and I'll certainly be experimenting, but this setup worked for me.
