Noise gating troubles

[spawnofthesith]

Hey all, I have an ISP Noise decimator pedal, and have been having some difficulties optimizing silent running at stage levels. Compared to my ENGL, the mark V is amazing silent without any noise gating, but there is still some very noticeable noise when I am not playing. Running the decimator out front cuts a little bit of the noise, but not much, and I tried putting it in the loop, but that actually made the amp noisier (that had me scratching my head :lol: ) so how do you guys run your noise gets for optimum noise cancellation? thanks

I run my decimator last in the chain right before the input, at about -40dB. Works wonders.

I noticed that too when I use the decimator but I do not believe its the fault of the pedal. I think that the MV produces some hiss to some degree because of how high its harmonic characteristics are with the gain on Channel 3. I use mine at about 4 on the threshold too and it sounds amazing. Just normal amp sounds when your not playing when you use it at loud volumes. The ISP is the only pedal in my experience to tame any MESAs.

Same thing here. I ended up selling mine, the noise gate in my M13 was almost as good and is out front anyway.

It has to do with the power supply to the pedal (9v or AC).

can you explain?

I sold a decimator to buy the G-string, and when i first tried it (in my noisy 5150), it failed miserably, adding all sorts of noise in that loop.

haven't used it since, and feel like a fool for selling the decimator, which i used with every amp. have yet to try it with the mark v yet tho...I can see it coming in handy if it works...

but are you saying the AC causes noise, or the battery??

In my case it was the AC adapter that was causing the noise. When I used the battery, the added noise disappeared. This of course after a lot of head scratching, cable swapping, and cuss words. :lol:

+1 i have one but have not needed one and i've owned the amp for 6 mo now. granted i haven't played any loud gigs @ bars w/ bad power, but that's also where a good power conditioner/voltage regulator would help.

try also with something like a voodoo lab pedal power 2+ (anything with a good linear regulator at the back end) that doesn't have a switching supply in there. one spots & bad wallwarts come to mind. also, if you run other things on the daisy chain, like a boss tu-2 tuner, the addition of a basically a computer, ime, has caused considerable noise.

battery is always the 100% noiseless source because there is no chance for emi, ground loops, etc. to be an issue. the only problem you might have is too much sag on the source, but that might be good for certain things like vintage pedals. (again, pedal power 2+ covers this area too). i've opened up some supplies and they are god-awfully designed. and i'm in power electronics. gl with your further decimator endeavours!
