guessing he was using that "Awful Yamaha vocal processor."

:
Play nice, old man. No one said the processor was awful ... just the harmonizer!
To be fair ... even that’s not what I’d call awful .... just extremely limited, and a bit illogical, compared to the standards that we’re used to. I like the way the mic sounds in my SX ... I just can’t perform the same harmony stylings that I’m known for because of the limitations.
