Doesn't the E60 have a vocal harmonizer in it? I do sing.

Also, do must music stores carry it. I was in Sam Ash last week and they didn't have it.

Has anyone played the E60 thru an mono amp? I'm using the PSR3000 and as much as I think this is a great keyboard, I'm totally unhappy with the piano sound which I use allot.
Nowadays I don't know if there is a keyboard that would sound good being played thru an mono amp...unless there is an amp that will do the trick?
