If you guys get together to try the Digitech Vocalist Live 3, I'd be interested to know how it turns out, especially the idea of splitting the guitar signal. Passing that guitar signal through the box concerns me as to possible alterations in tone. It is for certain that the guitar signal goes through some of the circuitry in the box. I really doubt there is true out of band sampling going on, but I could be wrong.
Any thoughts as to splitting the guitar signal? I would expect it to reduce the signal level going to the amp and the other effects and that will have some effect on the resultant tone. So not just a question of will it work without the guitar passing through the box but how well the guitar performs in that configuration.
I have been looking at two boxes, the Digitech Vocalist Live 3 as well as the TC-Helicon G-XT. Listening to the demos on the web, it appeared to me that females voices seem to sound a bit better. When male voices are put through the box, I feel like the resultant sound is a bit "digital" or "robotic" sounding. I would be using it to bolster the vocals in my little band... with a single vocalist, me! Not planning to use the pitch correction feature, just the harmonies. If you have recordings of you playing in the group setting and using the box, it would be cool to hear them.
I will ask Bobbyg if he is using it with an electric guitar? If so, does the guitar have active electronics or passive pickups? If acoustic, then I have a feel for how the thing works with the different tone characteristics as well as pre-amps for acoustics so equipped. I am a bit nervous about the signal levels when using passive style pickups.
Thanks and good luck with the investigations...
