I recently picked up a American Deluxe Tele (love it so far). But I'm getting some nasty 60 cycle hum or ground loop hum in several scenarios. I'm trying do some recording with it, so having that hum on a recording is especially frustrating.

I've done a lot of testing and narrowed the cause down to having anything in my chain plugged into my house's electrical system. The hum presents when I run directly into my amp from my guitar, through my pedalboard into the interface, with the computer running off of A/C, etc etc etc. I tested two other guitars which are doing the same thing, but I was under the assumption that the N3 pups on the Deluxe were supposed to be quiet (which they are when I'm completely isolated from the electrical system). As is typical, I can touch the bridge, strings or anything metal, laptop and interface included, and the hum goes away. The only scenario in which I have zero hum (touching the guitar or not) is running directly from my guitar into my recording interface with my laptop running on battery.

Anyone have suggestions? Would a power conditioner with isolated banks solve the problem? I'm losing my mind. Tried recording some slide guitar last night and kept getting this miserable crackling if I didn't keep a good connection between the metal slide and strings. :(

Thanks for any advice...

You try may guitars ; so it look it is not the guitar !

What about the amp ? hum or not with no guitar , nothing plugged in it ?

Try the amp and guitar in another home.

Power conditionner ? I don't know.
What about you house wall outlets , ground are working ? , you have to test it.

Questions: Are the house outlets grounded? Is there a dimmer switch for lighting, anywhere in the house?

As for those power conditioners, IMHO you'd need state-of-the-art lab level gear to get rid of the hum; it's probably caused by the electronic system of the building.
The guitar appears to be OK if the hum stops when you touch the metal.

True. All my guitars exhibit the same hum / buzz.

The amp is dead quiet, other than what's normal, with my guitar volume down, as soon as I turn up the volume on my guitar, hum galore.

Yeah, I'm trying to think of a friend / family member's house that wouldn't mind me making noise for a couple of hours.

Haven't tested the outlets. That's next, I guess.

Great question. I need to find a tester. No dimmer switches that I know of...

Would a power conditioner with filtration / isolated banks work? Looking at one made by Monster.

Did you try no guitar plug in the amp as I ask you ? Nothing plug.

Play with the amp volume to hear

Are you looking for this one ? This is only a surge protector.

You have yo find what is causing hum before buying some gadget wich may not work.

Look It is something coming from the air and guitar's pickups act like an antenna.
Halogen lamp , cell phone , PC , neon lamp , electrical motor running ......

A power outlet check is a must too.

I considered the pickups until I ran my guitar directly into my recording interface without my laptop or anything plugged into power. The guitar is dead silent in that scenario. The moment I plug something into power, I get hum.

Yes that is was you write first.

Recording interface may not have same gain than amp guitar. To me this not mean it is not the guitars. Not shure what is is. :(

More tests are needed.

Perhaps you've had encountered a ground issue or defective pickups. I suppose your guitar is under warranty.

Something wrong went with the wires. I suspect an improper cavity shielding.

There are also numerous other major factors responsible for the 60-cycle buzz such as a faulty guitar cable.

It sounds like you are describing a fairly slight hum that your guitar is picking up from electrical interference through the pickups, and not the type of hum that would be associated with standard single pole pickups, as your pickups are noiseless, stacked humbuckers.
If you are too close to your computer, amp, a television, a dimmer switch or other electrical equipment, a small hum can occur which can change in intensity by moving the guitar around, and which may be greatly reduced or eliminated by touching the strings, bridge or metal control knobs, which provides additional grounding.

The problem is not in your pickups, and it is unlikely that you have a shielding problem.
As you know, you can't shield the front of the guitar.
Since the hum also occurs when you plug into directly into the amp, you are probably picking up electrical interference in the atmosphere.
As noted in a previous post, when plugging directly into your recording interface, it probably has too little gain or volume for the hum to be noticeable.

It is often times difficult to completely eliminate 60 cycle electrical interference hum, even with noiseless pickups.
I assume that your American Deluxe Tele is fairly new, so I doubt that you are experiencing a true ground loop hum.
As Chromeface suggested, make sure that you are using decent quality guitar cables that are in good condition, testing different cable to see if that eliminates the problem.
While recording, I would only have as many pedals in your line as are absolutely necessary.
I also doubt that a power conditioner will do you any good, as it is doubtful that your hum is being generated by your electrical connections.
You could test your outlets to assure that they are grounded, but I assume that you have three plug outlets which are grounded.

Since I think that your problem is caused by electrical interference, my advice is to move away from your computer, amp and any electrical appliances, even moving into a separate room while recording if possible, while turning off as many electrical devices as possible.
You could also try running a ground wire from your metal control panel or control knob, taped to your wrist while recording, to see if that helps to eliminates the hum.
You could add a 1/8" mono male/female plug and jack on the ground wire to be able to quickly disconnect.
I hope that this might help.

After more testing and searching, I definitely think it's a grounding issue. At band rehearsal I can pick up EMI from other equipment on stage, and get it to stop by turning away from it. But the ground hum is always there, touching metal on the guitar or not.

I called and Fender and they told me to take it to my only authorized service center--Guitar Center. Their tech pulled the control plate off and he and I looked inside. Nothing amiss, as far as he and I could tell, but we tested another Deluxe Tele in the store and it had zero hum. When I got home I looked up a American Deluxe Telecaster wiring diagram and found this.

http://www.tdpri.com/forum/attachments/ ... wiring-png

There was absolutely not a ground wire connected to the control cavity in my guitar, as that 2013 diagram shows. So did Fender screw up at the factory, or has their wiring changed since 2013?
