presvis Posted October 17, 2011 Share Posted October 17, 2011 Hi I have a gibson custom les paul 1991. I recently swapped the bridge pickup for a seymour duncan distortion sh-6. I noticed with medium gain it makes a weird feedback/squeal/microphoning sound and i dont know why. ( i put a golden pickup cover on the new pickup to match the old one). Any ideas and suggestions??????? Thank you Link to comment Share on other sites More sharing options...
Flight959 Posted October 17, 2011 Share Posted October 17, 2011 Have you tried adjusting the pickup height?? Link to comment Share on other sites More sharing options...
presvis Posted October 17, 2011 Author Share Posted October 17, 2011 Have you tried adjusting the pickup height?? Yes . I did. The pickup height is rather low. Because its a high output pickup and i know that it shouldnt be high so the height is aproximately 3 mm Link to comment Share on other sites More sharing options...
Flight959 Posted October 17, 2011 Share Posted October 17, 2011 Is that 3mm between the pickup and the strings?? Link to comment Share on other sites More sharing options...
presvis Posted October 17, 2011 Author Share Posted October 17, 2011 Is that 3mm between the pickup and the strings?? Correction about 2 centimeters away from the strings Link to comment Share on other sites More sharing options...
Flight959 Posted October 17, 2011 Share Posted October 17, 2011 You could try remounting the pickup.... For the sound your getting its usually on pup height or poorly mounted.. :unsure: Link to comment Share on other sites More sharing options...

cjmwrx Posted October 17, 2011 Share Posted October 17, 2011 I have shorten the springs in order to get them back in . because i was trying without success because they were too long. bu they still have tension.. Shortening those springs could be your issue. Compressing those springs to get back on is tricky, but they are long like that for a reason. If they do not have enough tension on them, they can and will make noise. And, they need a lot of tension. I had the same issue occur with a Mexican Telecaster I put a Seymour Duncan humbucker in. I trimmed the spring because I could not get it back on. After several issues, and a trip to a tech, the resolution was to put the right length springs back in to get the right tension on the pickup mount. Then my squealing went away. It's amazing what vibrating spring will produce. Link to comment Share on other sites More sharing options...

martinh Posted October 18, 2011 Share Posted October 18, 2011 A few things to look at: [1] Is the pickup cover touching the side of the pickup ring? The springs and screws isolate the pickup from the vibration of the guitar body. This is undone if the pickup is touching the mounting ring [2] is it more microphonic to the touch that the prevous pickup, e.g does tapping the pickup make a louder sound through the amp? if so, is it equally loud when the screws are removed? If removing the screws makes no difference to the amount of microphony, it's probably not a spring issue. [3] are the coils screwed to the base of the pick up. If so, are these screws loose? [4] if none of this works, then you probaly need wax potting, as previously described in this thread. Link to comment Share on other sites More sharing options...

Angellus Posted October 19, 2011 Share Posted October 19, 2011 Springs? I've been using surgical tubing for years now. Decades. I thought everyone did. rct yes I've used surgical tubing on the bridge position with no problems. sometimes the springs do not compress enough to allow for correct height adjustment and rather than cut the springs i use surgical tubing. older PUPS tend to have longer mounting legs than the newer PUPS so sometimes you have to be creative during set ups. I have also cut springs before and not had issues. However I was interested that others have Link to comment Share on other sites More sharing options...
badbluesplayer Posted October 19, 2011 Share Posted October 19, 2011 S.D. pickups have different wire colors than Gibson PU's. Are you sure you wired it correctly? Which wires did you hook up to where? Link to comment Share on other sites More sharing options...
btoth76 Posted October 19, 2011 Share Posted October 19, 2011 Hello! I had two Epiphone LPs previously. Both were squeling like hell - even at moderate gain levels. Replaced all wires with better quality, shielded ones and that solved these issues. Cheers... Bence Link to comment Share on other sites More sharing options...
badbluesplayer Posted October 19, 2011 Share Posted October 19, 2011 Maybe the cover is resonating against the pickup. Try taking the cover off and see if that solves the problem. Link to comment Share on other sites More sharing options...
