have you tried a ground lift? I have used that on our PA and it kills the 60-hz hum. You can get them from home depot for like 30 cents. mine is a grey plug that i plug my power strip into, and then plug that plug into the wall.

I was plagued with a hum for a couple of years. I recorded a lot of guitar with that hum and had to use gates and clip editing to remove it. I got fed up with it though. I tried to clean up all the electrical plugs and electronics. Got rid of all non-essential electronic gear from the area. I plugged everything into an expensive power conditioner. No change. I finally tracked it down to a switch on an electrical chord that would turn on and off my powered monitors. We have a lot of dimmers in the house which I suspected, but those didn't matter. Nor did the power conditioner.
I now have absolutely no hum. I now use a Gibson Les Paul and a Fender Strat (new style pickups).

While this isn't the end of the world, it's not terribly wise either. Those 3-prong to 2-prong adapters are designed not to defeat the ground, but to use the screw on older wall outlets as the ground. Now, will using one vastly increase your risk of electric shock? Probably not. The only thing that should be carrying current is the hot wire. The neutral should go to ground. In practice this doesn't always happen. Chances are that you are still grounded when defeating the third prong, but it is less safe to do so.

I suppose in theory you could get shocked. We've used a ground lift in our church for the last several years and haven't had any problems, zaps or hums. I'm not saying it's the best answer, but it definitely works. :)

Hi, 6StringGeek, I can assure you that, if you're using the typical ground lifting plug adapter and don't have it connected via the small metal loop to a known ground, you *can* get a rather nasty shock. I know this from very painful experience. You obviously have been lucky so far, but one day your luck may run out. Like if you're playing an electric guitar and let your lips touch a microphone that you're singing into. I certainly agree that using a ground-lift adapter is *effective* at getting rid of noise and hum, but it does present some very real risk to your well being. If it were me, I'd get rid of all ground-lifters and make sure all equipment is properly grounded for safety. There are other ways to deal with hum than ground-lift adapters. Best regards, Bill

I initaly had no 3 pronged outlets in the house. I set my System up in my bastment and I use some verry old Equptment Like my Fender PA100 for an example. Beleve me when you stand on the concreate with no shoes on you will be shoked as the Ground path is no longer the nuteral.
I finaly got around to rewireing the place after my cousin came over. We wher recording one of his new songs and the first time he touched his lip to the mic he squaled in pain, I still have the recording for any of the doubters out their.
On a side note a good way to eliminate RF noise in a single room is to use Wire mesh screen or Aluminum foil under wall treatments, I had created a small room in my bastment for justr my computers to eliminate the fan noise. My girl freind then bought a wireless system for her keyboard and mouse and wow could I hear that in my recording room. I when to menards and purchased metal screen mesh and put it on my walls then coverd that with Wall treatment. All the wire mesh is grounded. It made a massive improovment.

some guitar direct boxes have ground lifts built in. it has helped me with the same issue. not sure if this is dangerous, it's not a ground lift on the power cord, but rather just the guitar cable.

CRT's are the worst cause... second cause is almost any other digital processor...particularly cheaper ones with backlighting displays, IE most digital rack equipment.

The ULTRA-DI DI400P is designed to connect a guitar or bass directly to a mixer without losing sound quality due to impedance mismatches, long cables or cycle hum. It allows simultaneous conversion of unbalanced, 1/4" jack input into balanced XLR output and routing of the instrument signal to an on-stage amplifier.

Hi, Duojet, I believe that the ground lifts on most direct boxes and other similar devices are perfectly safe to use. I've got a Radial Pro RMP that has a ground lift that is safe to use. I also have a couple of Ebtech Hum Eliminators that not only work really well, but are totally safe to use. I'm only talking about using the 3-prong to 2-prong adapters that we've all used on our amps, etc.. These things, unless the little loop is attached to a good ground, are *not* safe, even though the vast majority of people using them have never been shocked. I have been shocked on more than one occasion and I've given up using these little adapters for that reason. And, I've been playing/messing with recording for 37 years. During that time, I've learned a few lessons the hard way..... ;>) Much better to be safe than sorry, as it were. Best regards, Bill

I really like the Jazz Bass and I think new pick-ups would be the solution there. I wonder if custom pick ups would be a good idea for a Fender Squier. I wonder if it wouldn't just be better (maybe even cheaper) to just get a different electric guitar with humbucker pickups. What do you think? Also, where do you all recommend that I buy as far as brands of pick-ups and where?
I had Fender Custom Shop pickups (around 175.00) put on my Mexican Jazz Bass. I got them at GC. They didn't help get rid of hum though. My Telecaster hums also but not nearly as bad as the Jazz bass

Gearslutz.com appears to be down right now, but in their tips and techniques section there is a post about eliminating the buzz that occurs to some guitarists sometimes when you take your hands off the strings. This is a grounding issue but have a look anyway.

A] Get a three prong tester and make certain that ALL your outlets are correct in polarity and grounded.  B] If your guitar amp does not use a THREE prong plug have it altered to correctly disable the polarity switch and to connect a three prong powere cord in correct polarity and truly grounded. C] If all your eqipment is properly grounded you cannot get shocked by having your strings grounded. If you get a shock when your strings are gounded it is absolutely certain that something in your set u is not properly grounded or plugged into an outlet that is wired incorrectly.

Ah - is *that* why that happened? I'm getting nostalgic for the dive-bar metal-band gigs of days of yore.
