"Unwanted noise"

[Bozer]

What can I do to stop unwanted noise on my dual rect. in extreme high gain settings on channel 3? I have a boss ns2 in my pedal chain, but it doesn't seem to help. By the way this is only a problem when I am not playing. (in between songs, guitar volume at 0)

switch to ch1, noise suppressor isn't going to shut up your amp when sitting on a high gain channel, nothing to do with signal.

Are you running the noise suppressor in the loop, or in front of the amp? It won't do much in front because the high gain then comes afterwards.

If you use it in the loop and you can't set it so it cuts off then noise enough because it interferes with the note attack and tail-off, I think you can run it like this: guitar > NS-2 input; NS-2 send > amp input; amp FX send > NS-2 return; NS-2 output > amp FX return, ie putting the amp's preamp in the NS-2's loop. I haven't tried this though, it's a long time since I used a noise suppressor. You would have to put your other effects between the amp and the NS-2 in both loops. This is getting really complicated though, and could potentially cause ground loop issues as well.

If that doesn't work I think you may just have to do it manually as volatileNoise said...

Yeah, best way to reduce high gain-noise is to put an noise reducer into your fx-loop.

I have tested an ISP Decimator (only in front of the amp) a while ago, and it definitively rules. You could try it out, or get the G-String version, which has inputs/outputs for both in front of the amp and the fx-loop.

Sounds like you have the same issue I had a little while ago with my ISP Gstring. Your NS may be creating a ground loop. Test this by unplugging all pedals out of your chain and see if you get the hum when using CH3, guitar vol down, Output turned up.

You can make (or buy) ground lift instrument cables, but then you run into the problems of using ungrounded equipment. Not safe for you or your equipment and your signal will pick up RF interference.

The better option is getting a Ground Loop Isolation transformer. I got the Behringer HD400 HUM Eliminator, other companies make them as well but the Behringer is top notch for half the price. Real useful passive device - When known how to use properly.

When you hook this up, you will want connect in your chain like this:
NS Output > HD400 in/out (1) > Amp Input AND
NS Return > HD400 in/out (2) > Amp return

Note - In between songs.

step on another channel, you can't sit there with all that gain and output power on ch3, and expect it to be silent.

ch1 is my idle channel between every song, to shut the amp up.

compare your amp with a high horsepower V8, just cause you've stopped at the lights, doesn't mean it will be silent! :lol:

I just run my NS2 last in my chain going into the amp, and I can play (with a boost pedal) at high volumes on large stages and my Recto rig is still dead silent standing in front of it.
