      Same here, no pics.
      I want to go out nice and peaceful in my sleep like my grandfather, not screaming and hollering like the passengers in his car.

        Check for a loose ground wire in the cavity, check the jack connections too.
        Really? well screw Mark Twain.

          It buzzes even when the volume is turned down on the guitar, but stops if you touch strings/knobs/bridge? That seems strange.

            Sorry about the pics, I moved them from their original location thus the link was no longer valid.


            I just did what I should have done in the first place, try the guitar through different setups, with no noise gate or hard gate, directly connected to the amp.


            The buzz is still there, even with both volume knobs turned completely down.


            The only thing I can think of, merely out of logic, is that since the buzz doesn't depend on a specific volumen knob, nor a specific pickup, perhaps the problem lays on a common part of the circuit. That's all I can come up with now.


            The last pic shows where the ground connection is. It's not the best connection but is feels tight.


            I'm going to try and remove de plug connector and see if there something unusual there.


            Hope you guys might find the problem. Thanks for your time.

              Try to screw the bundle of ground wires tighter in the body.
              Check the ground wire to the trem claw too.

                Check the amp and outlet too, fluorescent lights and older TVs can have an affect if they're close.

                  My vacuum cleaner intereferes with the TV.

                    Perhaps it might help if he plugged the guitar into the vacuum cleaner?

                      Checked both with no improvement.

                      I connected the guitar to the laptop using usb connection and still had the buzz.

                      Again no change on the sound.


                      I checked the whole circuit following a circuit diagram from Seymor Duncan, I saw some differences but I'm not quite sure if that would be a standard connection with possible alternatives.


                      Anyways, thanks guys for your time. If someone has a different idea or might think about trying something else please let me know.

                        Once there is a grounding issue touching anything will ground you which causes the buzz to stop. Have you pulled the input jack and checked the wires and solder connections there? I've had two guitars with buzz issues and the problem was at the input jack.

                          It's hard to tell from the pics, but it looks like the 3 pots are connected together by a black ground wire, and maybe also connecting to the switch, but I do not see where any of them are connected to the grounding screw.
                          Basically, each component (pots, switch, pickups, bridge) should have one (and only one) route to get to ground, which in the case of guitars is the sleeve of the output jack.
                          If any of these components does not have a good path to ground, it will hum. Likewise, if there is more than one path to ground, you will have a ground loop which will also hum.

                          If you have a multimeter with continuity checking, pull out the output jack and put one probe there, and touch the other probe to each component and check for continuity.

                            All four componets are conected, but they're not linked to the grounding screw. 3 cables end up at the grounding screw, and all 3 come from the pickups and the output jack as can be seen on the second pic of my first post.

                              Kind of a not so right way to do this, but it worked for me.

                              I had an issue like yours. I got a piece of wire and rapped on end around the ground screw. Then with the guitar plugged I.and buzzing I started touching components with the other end of the wire. I eventually touched an item and the buzzing stopped. It had a bad sauter joint.
