Interferance Noises

Has anyone came up with some type of simple "filter" or something that aids in getting rid of interferances such as floresant lights, ground loops, this and that ? Some spots are worse than others.

I keep humbucking pickups on one guitar and SC's on another. Thats the only thing that seems to work for me. Some places are quite some aren't. There are some places where I can't use my Evans pre-amp. I don't pretend to understand all of this, I just know which rig works where. My Legrande with George L's E66, Goodrich 120 and 1978 Session 400 is the quitest rig I've got. It is quite under the worst of electrical conditions. My Evans equipment sounds really great but is more sensitive to bad electrical noise. I'll be curious of the responses to your post. Thanks a lot.

Each problem requires a separate approach. There is no "one fix" for everything.

You have to handle whatever problem there is on a case by case basis. e.g. noise may be getting into the system through the AC line at one location but what sounds like the same noise may be getting into the system from radiation at another.

Get one of these to start with...

I wouldn't suggest ordering this model becuase it is very expensive.

But you can find these at the local hardware store for around $20. Just make sure it is the type with the built in EM and RFI filters.

These filters will help to elimate buzzing from floresent lights, dimmer switches, the furnace fan and the neighbor across the street using his power tools in the garage.

It's a good place to start.

The built in surge protecter is a must for protecting your electrical gear.

As a tech.....
All I can say is:

"You cain't get there from here"

There isn't anything that wil get rid of all the problems encurred,due to electical noise,etc,etc in one single bound. Each has it's own methods. To the average picker,this is a problem that we all have to endure. As more tham often, the places we play,don't even begin to understand EMI and other sound problens we have to endure..... <FONT SIZE=1 COLOR="#8e236b"><p align=CENTER>[This message was edited by Bill Crook on 11 January 2002 at 06:52 AM.]</p></FONT>

Bill, we think alike. Both of our answers said about the same thing.

Also, from my experience at a large government agency, the low end or "consumer" variety of surge protectors and filters are a waste of money and gives a false sense of security.

Plus most of the RFI is induced at other points not the AC power input.

Mike---I stopped by Radio Shack today and they had several surge units with filters and I got the best one they showed for filter ratings . It has both the EM & RFI filters with a noise attenuation level of up to 55 dB. It sure did virtually eliminate my noises here at the house anyway. It remains to be seen how it will act elsewhere. Thanks so much for the suggestion !!! Bill.

First thing I learned at gigs...

Always turn off those little neon lit beer signs they hang in the windows.
