Petrosrock Posted January 16, 2011 Posted January 16, 2011 Hello people, I have a question and I would be thankful if you could give me some answers with this. I have big amounts of noises when I plug my sg into my marshall and turn the distortion on something that didn't happen with my ex amp. Is it because of the sg or the amp? Can I do smth to fix it maybe? Thanks in advance, Petros.
Petrosrock Posted January 16, 2011 Author Posted January 16, 2011 I 'm not sure if I can explain, it's a kind of parasite noises like "zzzzzz". The more distortion I use the louder the noises are.
bigneil Posted January 16, 2011 Posted January 16, 2011 There will always be a little more noise when using the distortion channel, it sounds like you are hearing the 50 or 60 Hertz buzz from the mains electricity supply. This Buzz will be greatly enhanced if you are standing near a tellyvision or computer screen of if your guitar or guitar lead has a dodgy earth connection. Have you tried a different lead, and have you tried a different guitar so that we can start eliminationg possibilities?
Petrosrock Posted January 16, 2011 Author Posted January 16, 2011 Yes man, yesterday I tried the amp with an other guitar in the guitar shop and there was no such buzzing, but I also tried my guitar with a different amp and there was no buzzing there also. So not sure if I cant tell amp's or guitar's problem, maybe both of them. Now I moved away from the television and computer and it worked, the noises were way less. Any ideas what else should I do? Shall I go change something at my guitar's pluging hole? (because you spoke something about earth connection or I 'm mistaken)
bigneil Posted January 16, 2011 Posted January 16, 2011 The guitar may not be properly earthed.. does the buzz become much louder and quieter if you take your hands on and off the strings? if so, it would be worth taking a look in the control cavity to see if there are any loose wires
Petrosrock Posted January 16, 2011 Author Posted January 16, 2011 Yes, whenever I leave the strings it becomes louder! What should I do with the cavity man? ;)
bigneil Posted January 16, 2011 Posted January 16, 2011 take off the plastic cover on the back and look at the wires inside to see if any are loose
Petrosrock Posted January 16, 2011 Author Posted January 16, 2011 I opened it and the result is that the wires are not loose but there are 2 cables without the plastic around them, they are naked. Do you think it has to do smth with it?
bigneil Posted January 16, 2011 Posted January 16, 2011 I doubt that the bare wires will affect things too much, they are probably earth wires soldered to the back of the Potentiometers...Is the wiring in the guitar the original factory wiring? Double check that the wire that connects the "hardware and strings" to earth is connected (Back of a volume pot' usually) this wire usually comes through a small hole in the wood. you can see it coming through a small hole in the top left of this cavity and connecting to the back of a Pot'
damian Posted January 17, 2011 Posted January 17, 2011 Shielding the cavity with shielding tape or paint may help....
Petrosrock Posted January 17, 2011 Author Posted January 17, 2011 I tried a new cable and it's exactly the same. Tomorrow I'm taking the guitar to the shop for a close look and fixing the bare wires. Thank you all for the information, Petros.
amx05462 Posted January 17, 2011 Posted January 17, 2011 the wiring looks fine check the 1/4 inch plug. push the positive contact in a bit. if its loose you were getting a poor connection if when you push it in the noise goes away replace the plug. 10 minute job 5 dollar part.
