MXR M 195 Noise Clamp

I use this pedal for noise reduction, when guitar is on stand by.
Pros:
* solid build quality.
* effect loop, allows to not include delay, reverb pedals out of the noise gate loop.
* clear instruction manual for proper setup
* decent prices (comparing to Decimator)
Cons:
* limited noise reduction - I would't use it for really high gain scenarios. Was trying to use on JVM410H, on high gain channels and some noise would still go through. Decimator does better on high gain applications.

I am disappointed by this pedal as the noise reduction takes a rather long time to come in effect: even a couple of seconds. Besides, the (only) control (for noise threshold) seems to have little or no effect on the pedal behavior. TO note: I have it properly connected (distortion unit in the send-return loop, and delay after this noise clamp) and the other two units in the chain are MXR (Carbon Copy and '78 Badass). I will try out more fiddling with the settings but I cannot see how to make it work as I expect.
