Guitar Feedback?

[13lackant]

hey all,

i recently changed pickup covers on my SG. from nickle covers to chrome, cos the nickle covers had very uneven oxidisation. anyway, after i switched it over, everytime i switch on a distortion/overdrive with relatively high gain, quite a lot of feedback is heard. very irritating, and its not the kind that slowly builds up, its the kind that straight away rings at a high pitch even when the strings are muted. anyone have any experience on this or how to fix it? my friend that helped me change it said its cos the output increases. anyway to resolve this issue?

thanks

Yea of course it will have feedback for the same amount of gain cause you have broken the wax seal when you changed the covers. You need to have it properly done and potted. It's not just simply cutting the solder attachments, prying off the old cover and soldering on a new one.

lower your gain pedals.

hey, thanks almondx yeah i think that might have been the problem. didnt give it a new wax coating. i think ill send it for proper servicing. btw just checking, how does the wax actually affect the sound and why's there feedback without it..? thanks..

leecs: yeah ive been living with very low gain for a few weeks. but sometimes when you need power, need to whack mah :/ and sometimes it gets even lower than the clean volume.

Hmm, it's a very subjective issue regarding potting pickups. Some boutique pickup makers such as Wolfetone do not pot certain of their pickup makes as they are a replication of the old school Gibson PAFs which aren't potted. Generally, a pickup is supposed to sound more articulate without potting but at the sacrifice of feedback. That said, if a pickup cover is attached on professionally without potting, the feedback should be so minimal that it does not matter that much.

The wax essentially forms a sealed barrier against microphonic feedback kinda like how the copper paint shielding used in the electronics cavity prevents the hum.

There's still many more facts about potting but my knowledge is limited in this area. But I hope it helped!
