At first I was very happy with this thing, basically it works as a true gate, shutting down the signal when it gets below a certain threshold, but due to an annoying soundfeature and an annoying functional shortcoming I've stopped using it.
In my setup (high gain) there is an audible squick/pop when the unit engages, which quickly began to annoy me.
The biggest problem for me is the lack of a mute option. The noisegate is the first effect on my board and the NS-2 from Boss that I had been using, and use again now, gave me the option to allow sound to run in the fx loop but mute the output. This allowed for quiet tuning during practice and stage sessions.
I may try again if they release a version two without the audible switch-on and with a mute option ;-).
