Softie Box Kit

[Cybercow]

I got a few of the Softie box kits while they were available and still have one left. (The ones I built are gone and I don't recall exactly how they behaved.) The question I have is: Is it JUST a bypass switch, or can it also be quickly double-tapped to go into non-lathing mode - like a momentary stomp. And then quickly double-tapped again to go back to regular latching mode? TIA
