Thanks. Well I'm definitely running my JTV59 through my POD 500x but on acoustic guitar models using just compressor, some Hall reverb and optionally a parametric EQ, no amp or cabinet models. Still doesn't sound as good as yours -- of course I'm comparing what I hear either from my powered speaker at home or in-ear monitors at church ( which is sort of direct ) . Oh and I recently bought the TC electronics VoiceTone Harmony GXT and liking it very much.
The only thing is now that I have a JTV and use only the VDI cable, one I bought separately, to use the voice pedal I have to put an effects loop effect in the POD patch so I can have the 1/4 inch cables running to and from the voice pedal.
We had a band rehearsal last night at church and with five footswitch presses I went from Rickenbacker 12 string through amp models on the first song, to stratocaster model through amps, to acoustic six string, back to the rick, and finally to a Tele neck pickup model. As we ended, I just had to kick on a ZZ top patch which uses the JTV Lester 2 ( les paul ) model through the POD "Purge" amp from the metal pack. Pretty darned impressive technology.
