My amp makes this static noise wich goes off as soon as i touch one of the strings or the metal part of the guitar cable. What can i do to make the noise disapear


This is a common problem... Make sure your amp is plugged into a three wire grounded receptacle. Keep the guitar away from magnetic fields of transformers in amps and effects units. Make sure you have a high quality guitar cable.

I have a Boss GT -10 and its great. When I plug in my Gibson les paul into it and play it, there is sound. When I plug in my Other les paul with emgs in it, no sound comes out. I plugged them both into...


The half-way cord is the clue. Read up on unbalanced and balanced lines and TRS connectors.
One of these requires TRS connections and the signal is being carried on the RING of the TIP-RING-SLEEVE connector. Plugging in half-way the TIP touches the ring pickup contact. The emgs one MAY use TRS type cables and there may be a reason the signal and hot of these are reversed. If I could find schematics on all this equipment I could unravel the exact cause. You could make an adapter with a Stereo 1/4 inch plug and a 1/4 inch jack by wiring it to swap the tip and ring between them to use for connecting to the emgs guitar. ALSO verify you are using the SAME type guitar cable for both.OFTEN a TRS cable will NOT turn on the electronics when plugged into a guitar. Use an unbalanced instrument cable unless you have the XLR type output. Use of an adapter from the XLR type cable into the Boss will usually not work.

Well i dont have a les paul studio i have a les paul menace with the same problem. Hopefully you can still help me. When i plug the guitar in and turn the volume up on the guitar a loud hum appears. ...


OK... Most of the guitars have a PAINTED on shielding in the well with the electronics. Sometimes the electrical connection to this is broken causing hum. Sometimes the connection is by way of the potentiometer shaft nuts and they spin and break the connection. This paint is conductive and often black know as aquadag. Use an ohmeter to verify connection.

My Les Paul Guitar hums loudly but when I touch a metal part of it with my hands the hums stops. How do I find the earth/ground fault using a multimeter?


You have a grounding problem. Verify your cable is good first, then open the guitar and look for broken wires. The electronic parts sit in a cavity that SHOULD be lined with CONDUCTIVE paint that acts as a shield and should have an electrical connection. You will likely find ground wires soldered to the back of the control pot cases. If you find a wire broken loose you have found the cause. There is usually a wire to the ground system from the metal parts.

Need to replace output jack and plate


If this is a classic guitar you should take the fretboard problem to a luthier as you could de-value the unit by working on it yourself.

The jack you can replace yourself. Just connect the wires to the new one the way they came off the old one. There are ONLY two wires. You can get replacement jack from severaal sources.

Les paul making wierd noises


Unless you are wanting to use the Nanomag, I'd just get it taken out of the signal. You should be able to bypass it anyways.

Getting Static noise when plugged in to amp


This is a very common problem that I have repaired for many friends. Sometimes the guitar jack becomes loose and gets rotated to the point where the wire breaks and/or touches the cord plug when it's inserted into the jack. You need to remove the access plate/panel at the back of the guitar body and see if the wire is broke or twisted. You may only have to loosen the jack retaining nut and rotate the jack to get the twist out or you may have to remove the jack and resolder the wire back in place. If its broke make sure to solder back on the proper terminal--the one with solder already on it and not the one that the cord plug touches when its inserted. Retighten the jack nut by firmly holding the jack from access side so it doesn't rotate again and cause that undesirable STATIC sound. Hope this helps.
