witterth Posted April 29, 2011 Share Posted April 29, 2011 (edited) The pickup cover on my MM (circa2005) keeps "moving up" when it does, it chokes the sound. string too close to pole pieces. neck looks straight, it beats the #### outta me whats going on. all is ok when I screw it back but it keeps (independantly) happening,curious as to why ,anyone else have this happen? is it just my luck? seems a bit "twighlight zone" cant work it out!! these are the only pics I have but wonder if they help, its the black,fretted one BTW,the fretless is fine, if underpowered by comparison. Ideas gentelmen? Edited April 29, 2011 by witterth Quote Link to comment Share on other sites More sharing options...
stingrayPete1977 Posted April 29, 2011 Share Posted April 29, 2011 Would a spot of lock thread (no pun intended today!) stop it from unwinding? Im not sure exactly what you mean, Is it coming unscrewed or could the threads be shot? Quote Link to comment Share on other sites More sharing options...
tommorichards Posted April 29, 2011 Share Posted April 29, 2011 It may sound like a dumbass question, but by pickup cover you mean the pickup? At any rate, try a slightly larger screw. Quote Link to comment Share on other sites More sharing options...

Curious now as to how they are held down I might have to go aand have a look...... Quote Link to comment Share on other sites More sharing options...
stingrayPete1977 Posted April 29, 2011 Share Posted April 29, 2011 Just took one out of my 2002 Ray4 and as I thought its a course threaded machine screw rather than just a wood screw, The spring behind should in theory push against the back of the cover and keep things tight but you know what Ideas in theory are like! Might be worth checking that the springs are in place though if someone has withdrawn them at some point and either left them out or they have moved into the pickup route when the screws were put back that would cause you similar issues.

stingrayPete1977 Posted April 29, 2011 Share Posted April 29, 2011 Sorry me again! Im not sure there are any screw springs on them anyway? They have the big ones on the back of the pole pieces instead (maybe aswell?) Whip it out fully and see whats behind is the best bet just make a note of the pup height on both sides first Quote Link to comment Share on other sites More sharing options...

stingrayPete1977 Posted April 29, 2011 Share Posted April 29, 2011 Im in the midlands mate, If you take measurements from the pick guard to the top of the pickup next to each screw you wont go wrong Quote Link to comment Share on other sites More sharing options...

stingrayPete1977 Posted April 30, 2011 Share Posted April 30, 2011 You will be fine mate and as for gluing stuff (lock thread) its just a tiny dribble on the thread before you put it back in, They will come back out easy enough next time as the glue is very brittle and just crumbles off and can be blown out of the cavity if you ever need to adjust anything.

witterth Posted April 30, 2011 Author Share Posted April 30, 2011 (edited) Ok then, Ill give it a go thanks Pete!! W still dont know why its happening in the first place though Edited April 30, 2011 by witterth Quote Link to comment Share on other sites More sharing options...
stingrayPete1977 Posted April 30, 2011 Share Posted April 30, 2011 Just the vibration alone will unturn a screw thats why lock thread is used on most moving parts of cars to stop bits falling off although you do need to check that there are some springs inside behind the pup and that they have enough strength left in them to push against the pup from below its only that friction of the casing pushing below the head of the screws that is stopping them spin out everytime you play. How far out is the pup? If you are a really light player maybe the springs are not long enough for the pup to be that far out and need a gentle stretch to gain the extra distance? Get it open and put up some pics thats the best bet Quote Link to comment Share on other sites More sharing options...
