Bernie,
I feel the vocal harmonizer s a great tool –but by far over used. I tried to use the unit as an addition to my voice, a section of a song that adds harmony voices for a short period. It takes away from hearing only my voice all night. Using the unit for a long periods will make it’s artificial more apparent.

When I began my career in music we had a large bass player who had a good voice, he did sing every song plus the repeats. My voice was just beginning to surface, when I was asked to sing, which might have been 2 to 3 times in an evening I received the longest and loudest applause – I did not have a better voice, they just enjoyed the variation, the change. This is my value on the vocal harmonizer.

What songs are best? Most any song, since you are only adding an effect it can be used anywhere in just about any song.

I do use the unit for a entire song when I feel my voice does not fit the venue of the song. Y.M.C.A. – I Will Survive – never on a Sinatra tune, that’s a no, no.

My impute, John C.
