Alright...after searching for quite awhile for a metal distortion that I like (been through various amps, pedals, preamps, etc.), I've settled on the Keeley MT2. It has a sound that is absolutely perfect for me, and is exactly what I'm looking for. The problem is: the pedal hisses like a mother****er. Very loud, and it feeds back really bad too. I've been living with it because it sounds perfect, but it's a real pain in the ass, and after trying to do some overdubbing with it the other day, I realized that the hiss needs to go away. I need recommendations for good noise gates and/or feedback suppressors.

The hiss is actually a note (kinda); there's a point of volume that's kind of between feedback and hiss, and you can hear that it's a specific note. I considered buying a parametric EQ and just killing whatever frequency that is, but I want to try noise gates first. The thing is the noise gate needs to work with other gain pedals too; I'll also have a NYC BMP, an Ibanez FZ7, and (in the near future) a customized Indyguitarist Sputter Fuzz in the chain at the very least. So whatever I'm using can't ruin those pedals' tones.

Also: when you give recommendations, tell me why you're recommending what you're recommending, and what kind of equipment you've used it with.

Thanks in advance!
