Feedback/Noise Reduction with Toggle Kill Switch Mod?

I've been looking at the alpha mod feedback loop.
And am trying to work out how to lose the NC jack and incorporate a toggle switch instead.

Am I right in thinking that placing a 2-way toggle that switches between the audio in and ground will act as a feedback/audio in/noise kill?
Any help much appreciated!

I think so, I might try the same thing.

am wiring up the parts now, but am just going to have a 2-way switch going between the input jack and the feedback pot. with the feedback pot all the way down, this should be the same as going straight to ground.
