Single Coil Hum - Part II

Post by Lee Baucum »

In the other thread about this topic Donny Hinson made this comment:
<SMALL>Grounding/shielding has always been a pet peeve of mine. Simply stated, if you can see the terminals on the pots, the back of the jacks, or any unshielded wire, the equipment wasn't designed with proper shielding in mind.</SMALL>
I would like to know what steps you guys have taken to increase the shielding on your guitars and how much success you had in your efforts.

I just had a 19.5k single coil installed by Jerry Roller. It is a TrueTone and I do not have any hum what-so-ever. I play under neon's in all my gigs and surrounded by ice and coffee machines at some. It is as quiet as the humbucker that came off. Last night I purposely turned everything up and laid on the volume pedal to see if I got a hum of any kind. There was none at all. I use a Lexicon for my effects so there are 4 loose sound chords that are each 10 foot long. A couple of years ago I asked the music store to give me the best shielded cords they have. Maybe this has something to do with it. I still remember the old days when I used to pick up every CB'r that passed by. We heard some pretty juicy conversations. I don't know what the secret is but I'm happy I don't have those problems anymore.

Rick, I am of the opinion you can gig just about your whole life with single coils and you may not run across the "EVIL" room...

notice I said JUST ABOUT..

The good thing is probably that there are only a handfull of "EVIL" rooms...

But they do exist..and when you unload into one of them and fire up the rig..

well...It ain't good....

Bought a Zum and eventually had to get rid of pickups. Steel was ok in the bars but when i tried to record I couldn't use the steel at all. The hum was unbearable. No neon or flourescents at all. I am happy with my humbuckers. I don't really understand why guys like single coils anyway. I don't hear anything special in the tone.<font size="1" color="#8e236b"><p align="center">[This message was edited by Ron Sodos on 07 February 2006 at 03:02 PM.]</p></FONT>

I resectfully disagree. The studio that I work in a bunch is a totally evil room. It used to be a radio station and there is a giant transformer that was installed to provide power for the transmitter amplifier among other things like air conditioning. I have a warehouse for my audio business and the transformer (you know those green boxes that set on the ground near commercial buildings) is located just outside the wall and I can't play a single coil steel in my own building!! I have recorded in a bunch of places that have tons of hum (AKA Electro Magnetic Interference or EMI) in the air. Last night, I took my '64 Emmons P/P to the set of a TV talk show. In the big city, tall bulidings, TV transmitters all over the place. Quiet as a mouse. But there were no power transformers nearby. I think that's the key to the evil. NEARBY POWER TRANSFORMERS.
