I bought a brand new PRS Custom 24, it plays and sounds fkin fantastic... But there is one problem -.-... it has a very loud hum whenever i don't touch the strings, this disappears whenever i touch the strings again. (Dead Silent when this happens)


My other guitars almost have no hum at all in comparison to the PRS C24, is it supposed to be humming a lot?

No, it's not supposed to be humming. It sounds like a grounding issue. Though I'm surprised that a new guitar of that price and quality started out with a problem.

Yeah im also surprised that a guitar in that pricerange has a silly problem like that... :/ Everything else on the guitar is just top notch

I'm guessing that it stops when you touch any of the metal parts?

it sounds like a bad solder on a ground somewhere.

Sean should be ashamed of himself.

just get it fixed at the store if possible. if you like everything else about the guitar a simple re-solder should fix it right up.

I just checked a youtube video about the problem http://www.youtube.com/watch?v=V4ohqmX6WvM&feature=related 1.20min and on he covers it pretty well :P Exactly what my guitar is doing atm XD!


I wish it was so simple :P Thing is i live in Denmark, can't buy PRS from anywhere but Germany so i had it shipped here -.-. And to return is isn't as simple as i would want it to be

Make sure all connections are soldered correctly, especially the ground/earth wire, and make sure the pickup and control cavities are shielded with either foil/copper tape or conductive paint. Most guitar companies seem to leave this step out of the building process, even high-end builders like PRS. Most of the time you have to do it yourself.

Yep, thats a grounding problem. Take it back to the shop. I guess that making a mistake like that in the PRS factory will most sertanly get you shot at dawn

Sounds like taking it to the shop isn't an option. He said he had it shipped from Germany.


T.S. A grounding issue like this can be as simple as a loose or broken wire / solder joint. If your comfortable doing so remove the rear cover and see if you spy any loose wires in there.

How can i tell if the guitar has conductive paint, without having a special tool? :P

Are you serious? It's a damn 5 second solder job. Reattach the ground. Done.

How can you be so sure that it's a grounding issue? I tried to check around the guitar couldn't find any loose ends? :S
#15
Because there's literally nothing else it could be?

Just because there aren't any blatantly loose wires doesn't mean that all of the connections are solid. There could easily be a cold solder joint somewhere.

This usually doesn't have to be done with Korean guitars, but eh... sometimes things slip through QC. Or, even more probably, maybe something came loose in shipping. But, a general rule of thumb on every cheaper guitar is that you should resolder all of the connections yourself. Especially on Indonesian and Chinese stuff, they are just kind of notorious for having terrible solder jobs.

The only way to know without seeing it is using the probes on a multimeter. Set it to measure DC resistance and touch the two probes to the shield. if you get a reading, it's conductive. If you don't it's not.

Looking at those pictures, the back plate and cavity ARE NOT shielded. Conductive paint is usually a black/grey color, and copper of foil shielding is, well, copper or aluminum foil.

This guy's video explains how shielding works, and how to test if you are shielded.

This video shows you how to do it. It's a really easy mod to do.

Hey, Did You Fix Your Problem? I Have The Same Problem With A Custom Tremonti, Im So Far Away From The Store, How Do You Fix It?
#18
I sent the guitar back to the store where i bought it, and they stated the problem was mine... and it didn't make any noise at their place. So i got it back and i was pretty annoyed.

I raged for a while and finally i got the nerve to take it to a local guitar repair guy, he said he would shield the entire guitar with copperfoil.

He also told me that the reason the guitar makes a lot of noise, is because i live in Denmark... And we have bad standards for ground in our plugs around the house. So this will give a lot of noise problems that don't happen in other countries! And shielding the guitar will most likely make most of the noise disappear... but not ALL of it


Now i just have to wait! Really hope this will fix my problem! =)

Woodstock in Århus sell PRS, they could probably fix that with ease. Though any music store should be able to.

I also have this problem with my 2012 PRS. I'm an electronics noob at best, and am unsure about which wire the ground is. I'd re-solder it myself, but I don't know which connection to re-solder.

I just got my PRS back from the guitar repair guy! Most of the electronic noise is gone now... BUT still something there, he told me it would be almost impossible to remove all the noise from the guitar, because of the way the pickups were wired... They were wired as single coil pickups so the humcancelling effect of the humbuckers weren't there. He told me

I might be able to reupload some pictures of the electronic cavity again sometime soon, so you can see what have been done !


AWACS, does the noise disappear when you touch the strings or any other metal part of your guitar?

Yeah, it does. I'm pretty sure its a grounding issue, I just don't know where to start with the wires and all that.

i suspected a grounding issue at the beginning aswell... BUT if the buzzing stops when u touch the guitar the ground should be okay i think?
