Well.................I am in the hate it camp
I thought the sounds were a little too electronic (only word In can use). Now to be fair, I have used better quality units before I used this one, so that could be it. They always state "It sounds just like the actual pedal" I never thought so.
I had originally bought it just to use at a blues jam but never bothered after playing with it. I did though find a good used VOX Tonelab ex that I actually do like and it will be going with me. Maybe their advertising is correct, with the tube in the unit makes all the difference.
I have heard that some heavy rock bands do use the ME80 for vocals
