I suggest any T2 owner/singer should get to grips with the T2 vocaliser as it certainly doesn't sound as bad as people make it out to be on here. I am not a singer myself but I've had a couple come round and I've tried it out with good results.
Fair enough it's no way near as good as a dedicated stand alone vocaliser unit, but it more than does the job as long as you don't go overboard with the settings. For solo artistes who can't afford a stand alone unit after parting with their hard earned cash on a T2 it is more than adequate.
Experiment with it and you will get results.
