For educational purposes/benefit, what is the difference between sending 2 versions of the mic to the same console or two separate consoles?
In the case of the vocal pedal being discussed, it lets you set the gain and eq for the effect separate from the clean mic. Since the pedal currently reduces the gain significantly this would be an advantage.
Perhaps a better option is a switch box which lets the artist decide when to use the effect and when not to. This takes that responsibility off the soundman. Whirlwind among others makes a footswitch that does this.
