Sometimes I get a buzz or some other unwanted noise coming through my amps. What's the best noise suppressor that won't interfere with the signal?

What kind of amp are you using?
What kind of pickup are you using?
What kind of cables are you using?
More info will help us help you out! Be as descriptive as possible about your setup and I bet you'll get some really great ideas from this thread.

Tim, I play an MSA Millennium, with a Tone aligner pickup, a Telonics volume pedal, a Sarno Black Box, A POD XT, and 2 ZT Club amps. And I use George L cables.
I don't think my gear is the source of the problem.
I think the problem is in certain venues where there is stuff in the AC line that gets into the signal chain.

You're already using a humbucker... so your continuing options are limited.
1. AC power filter... get a Furman rack box, etc that filters your AC. You can cheap out here, check out Corcom filters, pretty much what's in the Furman.
2. Use a noise-gate box... below a certain signal threshold it cuts off input completely. This doesn't help if the noise is getting inside your amp, obviously.

If both those amps are using their proper 3-prong grounded plugs, you may have a ground loop. The best solution to that is to use an ebtech Hum-X ground-loop eliminator on one of the amps. Read here for more - http://bb.steelguitarforum.com/viewtopic.php?t=146001
and/or just do a forum search in the Electronics section for the search terms ground loop.
If you want to see if this is the problem, just try using a ground lifter (3-2 plug adapter) on one of the amps temporarily - not as a permanent solution. If that fixes the problem, go get a Hum-X.
BTW - I use a Furman AR-1215 voltage regulator. It regulates the voltage just fine and I wouldn't be without it. But I have never found anything like this to reduce a bad hum in my sound. |

Mike, you're fighting a ground loop, like Dave said. Just use a 2-prong ground lift doo hickey on one amp, the hum will be gone. I used to do that all the time with my twin amps when I was younger and stronger!

Use the process of elimination and you will most likely find the 2nd amp or wall wart or both is the culprit.

never a great idea. That is a 2 prong ground *adapter* not a lift. Just be careful using one of those - back in my days as a live audio engineer I used to see bad things happen to musicians in clubs because of those. If I saw one, I would highly advise removing it and solving the ground loop on the audio side of the device, not the chassis/safety side.

| Do you have the noise if you just use one amp? That will tell you if it's a ground loop issue. |

The EH Hum Debugger and similar devices are notch filters that take out the 60 cycle hum by taking out a specific narrow audio band. Some people don't miss it, if you're playing in a band with some other electric guys it might not bug you. However, I suspect in your classical playing situation at least, you kinda live in that low end, from the clips I've heard. If it's just a hum that's annoying you in between songs, those plain old noise gates do a great job at what they do. Given the saturated environment we live in it's amazing there's not more noise. Do you realize that every TV station, radio station police radios and garage door openers and every cell phone user in Los Angeles are beaming waves through you RIGHT NOW?!?! AIEEE, AIEE, etc.  If you're getting just an intermittent buzz lasting a few seconds then going away, it's cell phones.

Warning: Old Joke
I tried putting a noise canceller in line with my guitar the other night...no matter what I tried to play, all I heard was silence!

Do not use more than ONE wall outlet.
Multiple wall outlets in different locations can go do different circuits and will cause groundloops. |

I have an EH Hum Debugger and it works great when you just can't live with the hum. However it does introduce a slightly weird random phasing type effect. Not bad, but you will notice it. All in all, I'd rather have it than not.

You also might try to seperate your power lines from your audio lines. I get buzz quite a bit, most of the time it's from crossing power lines over or under my audio lines.
I am getting the EH Debugger thou, I play a strat and it gets quite buzzy sometimes no matter what I do. |

I always have the EH hum-debugger in the gig bag. Minimal tone loss is worth cutting out the hum. It is not an exciting $100+ purchase until you need it. That is especially if you are doing some sweet long swells which is kind of what we do.

You might try one of the new power bars with suppressors. Plug both amps into the same power bar. This puts both amp ground connections on one ground bus and presents only one ground to the house circuits.

| I've found a fool proof 100% noise eliminator. The on/off switch on my amp! Highly recommended by my wife and kids. |

I built a hum eliminator for 15 bucks using a couple diodes and a rectifier. Works great. One stop at Radio Shack and another at ACE and good to go.

Here is the video! Ran it by one of the Electrical Engineers at work and he said no problem, just a little crude. Mine works great!
