DOD 230 Noise Gate

From the post

Here’s the build I’ve draw to use with some of my higain layouts like Dr.Boogie, or BSIABII. It’s unverified. It’s single knob gate with the switch – I have no bloody idea what switch does, I’ve downloaded the original layout long time ago and I don’t really remember from where, so no person to ask. From the picts of the original unit we see no extra switch, so this one is an mastery The idea of using this layout to me is to activate it without the toggle/stomp switch, just use a pot with integrated DPDT. In O position this circuit will be omitted, anything above activate the gate… Well, it’s just my idea to use it, this way you save a space, but doesn’t really matters how you use it really.

I’m not sure If this is any good for higain pedals, as I heard it’s to slow, may be some of you knows how to make it faster, or perhaps someone point me better single knob project to transform
