Yes, this piece is simply one of the best guitar noise gates I have ever used. I tried the Boss and Roland stuff but this is just perfect for the Send and Return loop of a big, heavy, loud and distorted Marshall JCM 900 – just like the one I got, actually. Anyway, Eric Clapton used this item for his Soldano/Cornish Guitar Routing System because Pete Cornish thought this might be a useful thing. It is expensive, yes. But again, if you want something that really works, you need to pay for it.
