I felt I should give this pedal a try when I had the bright idea of trying to play Porcupine Tree covers with a Fender Jaguar, using 2 overdrive pedals on top of one another. I have swapped the bridge pickup for a more high output model, but it's still a singlecoil, so it's pretty rife with buzzing.

Well, I only got this pedal today, and have been A/B-ing it against my setup without it all day, and have this to say about it. It does do as advertised. Switch it on, the hum is gone (some incidental poetry for you all there). The little toggle switch lets you take even more hum off should there still be some in your signal.

But...

I'm glad they don't add on the sales pitch that it doesn't colour your tone or words to that effect, 'cause it would be quite untrue, especially on the "strong" setting. It's not really apparent on "normal" mode when you're playing clean, it's really when you kick in some distortion. You get an odd metallic sound, less warmth, kind of... robotic, almost. It's wierd. Also you do get some note degredation if you try for some sustain (I think that's what the off button's for though, in fairness). And as I say, this all becomes more prominent if you switch the pedal to "strong".

Now, I for one think that people who seek to get "perfect tone" are really being quite anal in this day and age. With all the modelling amps and digital effects and crazy experimental music out there, who's to say what perfect tone is? It's an antiquated ideal to say the least, without any offense intended.

On that note I will say this: this pedal is good at what it does. While it does that, it has a little fun of it's own with your guitar sound, which may detract from the opinion of afore-mentioned "tone purists". And I will admit it is a bit annoying when you've got stuff sounding how you like it, but it can be kind of cool in the right situation (Johnny Greenwood fans would probably quite enjoy it), and it will probably go completely unnoticed in live settings when stuff's too loud for tone to be appreciated anyway.

All that said, I give it a 7, because while it is useful, it disappointed me that I would have to switch it off every time I want do some soloing. Still better than other noisegate-type pedals I've used, probably the best one anyone's making in fact.
