Hey Zilthy, care to share how you set that up? I was in the same predicament with rack gear down to a Flextone II in 2000 and now I'm back with tubes after all of those years. I still have two Flextone II XL's each with a 2x12 cabinet.
Regardless, I now own a Mesa TC-50, Pod HD Pro X and an FBVII and couldn't be happier with all of what the Pod HD Pro X has to offer and the MIDI capability. I only use the Pod for FX - no amps, cabs or mics but what a backup if I need it! Problem I'm having is all of the EQing, gain staging, Line, Amp, Stomp switches, FX and Loop placement and like you said "no metering". I'm running 4CM but with all of this flexibility I just don't know if I'm pushing too much here or not enough there.
To start I'm using a Tube Screamer, Volume, Wah, Noise Gate, FX Loop, amp disabled, mixer, chorus, delay and the looper is last.
It seems it sounds better with the FX Loop before the mixer. I've read it should be after the mixer with mixer channels at +6db, unbalanced out set to Line into the amp's instrument input and the FX Loop set to Stomp. The system is set to in front of stack although I don't particularly like the Mid Focus or the Treble and Bass cuts and it seems to sound better without it when I use the into an amp setting. And then there's the global EQ to mess with or turn it off - not sure if I'm going to use it or not just yet. All this EQing is a bit much.
Maybe you can offer what your setup is like just so I can get an idea of what other users are doing.
Thanks much.
