can any1 tell me how to do grounding for guitar feedback? i got soldering kits and a sg. that sg gives a very very irritating hum.. lol teach me pls
 
Have you ascertained that it's the guitar? And not the amp? Or the cable?

If it's the amp, a simple swapping of the two-pin to a three-pin plug would do the trick.
 
its the guitar.. confirmed alr..i tried to solder a piece of solder onto the tone and volume knob at the back and it solved the feedback for a few days, but it came back..
 
i think you should smash the guitar to pieces since its giving you so much trouble.haha.

okay the bridge should be grounded too.
 
dont play2 with grounding...if u r not sure, bring ur axe to a qualified tech... to avoid any mishaps.....
 
Grounding the bridge

The wires is only to check if the bridge is not grounded. If the humming sound disappear then you have to ground the bridge by running wires connected to the body of the pots and you have to do it inside the guitar.

Im afraid if the hum is still there then you have to check for the pots or the pick-ups.

By the way what brand is the guitar? type of bridge (fixed or tremolo)? How old? and is it repaired or serviced before?
 
eh its a epiphone sg, the metal edition.. the black in color one..eh its my friend's and she bought it 2nd hand at guitar connection a few years back..oh and pm the back of the guitar, the pots alr have some solder on top..

it looks like this.. the green and the black wire is soldered ON TOP of the bottom left pot.
and bottom right/ and top right pots have both a lump of soldering on top..
it looks like it has been grounded before or serviced but the hum is very very very bad. esp when u're touching any metal parts on the guitar itself. and the worse thing is once u plug it in the amp with dist, the feedback is very horrible.. lol its not the amp. i've tried it with my lp. confirm is the black sg.

Thanks for the pics.

Thank you for the pics it clears my doubt when i saw the electronics. The guitar is already serviced as shown. I think the aluminum foil is used for grounding the 4 pots ha ha... Anyway you have to do the soldering connection forthe 4 pots using additional ground wires, and oh... use the shielded wires so not to short any active components within the pots. As you have mentioned only 2 pots are connected by the green and black one.

Another question BTW, is the humming already noticeable when you got this guitar?

eh i dont think so..it just became worse. like from low hum to very irritating hum.. anyway, for the ground wires, i can get it from shop by just asking for "ground" wires? cos i have alot of wires at home.. and when soldering, just connect the 4 pots using the gound wires and solder them on top?
 
ground wire is named ground wire coz of the conenction to ground. It can be any sorta wire as long it conduct electicity and not too thick or over size as compared to other wire in your geetar.

usually for geetar work, people use multi strand wire coz its more flexible to work with. You can use single core type, but its less flexible(good thing is you can shape it anyway you like and it stay that way)

go thru those articles in the guitar nuts site. Those info in there are really useful and will help you in long run, by going it thru over, over and over again.
