It's that classic "one ten millionth of an Elvis" slapback delay.

I don't know how the PRS sweet switch claims to work, but a passive signal delay isn't really a thing
Like you, I can't even begin to imagine how this could work. But I did find the manufacturer. Unfortunately, you have to email them to get a data sheet. I think I will tomorrow.

I checked on these some years ago. As I remember, the minimum order size at the time was 5 units.
If you decide to order I'd happily chip in for one, and I bet there are others who'd be interested.
Whats the cost on them?
