[sdiy] OT: scratch filter for vinyl

[Stephen Begin]

I've seen some DIY projects in old magazines (if anybody wants I could scan
them probably) featuring a processor that eliminates pops from records...
As I understand they work by simply blocking the signal completely when they
encounter a pop, and since it's a very small silence it goes unnoticed
(supposedly).
I was just wondering if anybody has ever used one of these devices and if
it's worth building one.
