Best, easiest vocal processor?

Contributor - Level 1

So- im a bit overwhelmed with the amount of choices in live vocal tools. Im a bass player, i sing a little lead, and want to be able to do better leads and sweet backgrounds, I dont have a particularly awesome voice Smiley Happy but im typically in key, want something that is very easy, but makes me sound a couple of clicks fuller, tone adjustment,  I have a mic Mechanic, but looking for more- like duplication. I have a Harmony Singer- but it doesnt really work on bass, though i do love it for my acoustic.  Thinking a doubler, with reverb/echo, correction, ???? Has to be easy- not looking for soemthing i have to be a programmer to use.

Thanks for your help
