Phaser Question

I notice that the Phaser doesn’t have a Mix knob. Does that meant that there isn’t a way to use an expression pedal to change from a dry signal to a phased signal?

I realize there is an Amount control, but it seems that the signal is still modified with the Amount set to 0. Is this correct?

Thanks,
Bryan

the phaser is an all wet effect. the amount knob applies to the amount of modulation of the phasing frequency
