Permalink Noise Gate making rattling/scratchy noise when hitting higher notes...

New Topic
Page 1 of 1

I've got a cheap CNZ noise gate to try out (I'm not a high gain guy but I like single coils and don't want to hear the hum when I DO use gain). It worked fine until I redid my pedalboard order yesterday.

Now when it's engaged it's adding a strange papery rattle or hiss sound when I hit treble notes. When turned off it's fine. I have it last in line before my amp but it's also the last in line on a daisy chain.

Since its at the end of the daisy chain I'm wondering if it's not getting quite enough power to operate properly or something? It could also be that it's just a cheap piece of crap but it's just strange that I never had this issue until I moved everything around...

Or do I have it in the wrong order on my board?

I tried Googling but came up empty...

Any help is much appreciated!

I haven't had good luck with noise gates. I use a Boss NS-2 Noise Suppressor (analog), which works really well and is pretty much a standard, even the technology is old. Noise gates and noise suppressors function differently. It's are worth reading about the differences.

Besides in/out, the NS-2 also has send/return, so you can send distortion pedals (noise) through it and bypass non-noisy pedals. The send/return isn't really necessary if your amp has an effects loop.

I also have a Behringer NR300 Noise Reducer which seems to be a cheap knock-off of the NS-2. Controls are about the same, it has send/return and seems to work as well as the NS-2, which has been replaced by the Boss NS-1X (digital).

Sorry, but I can't address your noise issue.

Start checking with the common pain points - power and sound cables.

I think your thought that putting it last in the power daisy chain is a likely suspicion; those daisy-chain power cables are notorious for introducing noise into a signal path. Try powering it separately if you can, and replace the patch cables on either side of it.

Another possible problem is that you bought a cheap pedal. Not dissing inexpensive kit, but often the QC on those things isn't what it should be and problems can develop over time. Might be worth giving the nuts on the jacks a once-over for snugness, that kind of thing.

Something I started doing not long ago was putting my tuner last in the effects line. That way if my rig seems noisy, I can just tap the tuner on between songs and kill the noise - and have an excuse to make sure I'm still in tune!

Thanks guys! I knew there was a difference in gates and suppressors but never really had it broken down for me like that article did, so thanks for that.

I'm definitely leaning towards it not getting enough power. I think I'm going to order an extra 9v power supply from Amazon and see what the noise gate does if I plug it in by itself.

Or pretty soon I need to just pony up and get a good power brick. Those new Walrus Audio ones with 15 slots look pretty nice...

I already tried replacing the patch cables, no luck there. I'm going to check the jack nuts, too.
