VoiceTone D1 : Great for backing vocalists

When playing live one of my (many) roles is providing some backing vocals, and after a couple of gigs with a "new" small line-up I was looking for some "magic" to help thicken the vocal sound. Primarily sticking with the "group" setting it does indeed add some very nice "magic" and really does make it sound like there are more people singing. Sometimes it is subtle enough that I wonder if it's working but other times it is really clear that it is - volume seems to count! On one song I'm experimenting with the octave down feature (mostly to make my life easier but gives a "doubled" sound in the bargain), requiring a trip to the floor for a setting change, so would've like the wording a little larger but otherwise a very fine unit.
