NOTICE GLOBAL

I bought it to eliminate rumble made by my former prampli "mesa correct recording" in modern fashion. It was very effective!
Now I use the noise gate of my boss gt-8, so I have increasingly utility but I tried my jmp-1 produces a background noise OD2 mode and it is indeed also.
I also tried my PA to eliminate the feedback not provoked vocal mics (one channel of course) and it is very effective!
big default of this pedal is that it is mono.
