This is a straight noise suppressor with really only one purpose: and that's to suppress noise ! I believe it is digital. It cannot be edited via computer. This is a floor pedal, so it is not rackable. This unit has an input and an output for going from the guitar to the rest of your guitar pedal chain then to the amp. However, it also has additional send and return inputs and outputs, which essentially turns your pedal rig into an effects loop. This unit is definitely most effective when utilized in this way.
The general configuration/setup is simple. Sound/effects editing is easy. It's got two modes: one to mute your signal and the other is the actual noise reduction mode. It's got two knobs, threshold and decay. You need to tweak these two knobs to get the maximum, most effective noise reduction possible without compromising your tone and sustain, which the unit can do if you set the threshold too high. I bought this used, so I don't have a manual. However, I don't think it's necessary.
As said, this effect is for one thing and one thing alone. It is for noise suppression. It does what it does very well. It reduces hum, feedback, and other noise very well. I own a DOD Yngwie Malmsteen preamp overdrive pedal, and Yngwie himself will tell you that that little unit is noisy. When you put this pedal before the DOD in your chain, utilize the effects loop function. You can hear the wonderful sustain from the DOD without the annoying noise, as long as you don't set the threshold too high, thanks to the Boss Noise Suppressor.
I've been using this unit since the beginning of this year. I love it's noise suppressing capabilities. It's not the most glamorous pedal, but I feel it is an essential component of one's pedal chain. I don't know what I did before I bought this unit. The only thing I don't like about it is that it kills your sustain if you set your threshold too high. This is unfortunate, because the higher you can set your threshold, the better the noise suppressor effect. If you can be successful at finding a happy medium between these two factors, you will also be happy with the unit. I checked out rocktron's version, but nobody swears by their noise suppressors as much as people do with their Boss noise suppressor. The pedal is kind of pricey in my opinion, but since it is so essential to your rig, it is money well spent. I have no regrets about buying this unit. I needed it, plain and simple, and it does its job well.
This is a noise reduction stompbox for guitars. I never really thought about it but I assume it's all analog... Anyway the box is very sturdy, Boss-shaped and sized but WAY heavier.
Well, VERY basic setup with one mere single knob... But does it need anything more?
It doesn't provide the effects loop that its Boss counterpart does, though.

Well, all you expect from this noise reduction box is to... reduce noise, don't you? If such is the case, you can expect to be 100% satisfied. Whether it is a single-coil pickup noise or the typical hiss of a huge distortion box that annoys you, just find the right setting and you'll get your guitar sound -- your WHOLE guitar sound, NOTHING BUT your guitar sound. Hard to find a setting that will suit both your clean and saturated sounds though, so try to get a setting that is relatively hiss-free when distortion is off. It proved efficient in taming successively a SansAmp GT2 in Mesa simulation mode, a Zoom Tri-Metal (not too difficult though, this one has an integrated noise gate but the Decimator still removed whatever was left of noise), an EHX Metal Muff and a Big Muff boosted by an overdrive.
Since I don't use a proper amp I couldn't test it within an fx loop.

I've used this one for approximately one year now. A good addition to my home-studio-oriented rig, as it finally made exploitable some of the sounds that I'd been carving carefully for years (anyone who's played a GT2 in high gain settings or boosted a Big Muff will know what I'm talking about). A bit overpriced maybe (it did cost 169€ new if I remember well, but I got it used with the knob a bit messed up - but still usable- for 110 or 120 I think).
This is the first noise reducer I've used since the (very basic, sustain-killing) one that was included in my old multi-effects unit, and I'm really satisfied with it. Set it up carefully and it will respect carefully your guitar tones. Seems like a new evolution of it is about to be released, I can't wait to see what more it could bring (although I will most likely stick with this one which already perfectly suits my needs).
