Hi everybody!
I\m new here so it\s possible this question has already been answered.
 
Why are there always just two pickup screws on each pickup? There is space for four screws in each pickup.
 
Alembic produces the pickups. Why are there always    
four holes when they just use two??
 
Wouldn\t it look much better making pickups with two holes then?
 
Thx
Endryq
 

There are two screws under the empty screw holes.  To raise the pickup, loosen the visible screws, then unscrew the screws under the pickup until the pickup is at the desired height, then snug the visible screws.  Ingenious scheme which works better than any other I've seen...

Hendrik,

That explains the four holes in great detail.

in the beginning(early 70s) there were only two screws per pick up,and as you can see on (#12 here) the pickup height was not adjustable back then,height adjustment came along in the late 70s.

My pickup cover screws on my SC signature keep coming loose and i have had to tighten them down again this afternoon.
 
Any reason for that or a simple solution?
I sometimes rest my thumb on there to play over the pickup but not very often?

you might want to raise the screws on the 'under' side of the pickup,(the ones that arent exposed),so that the p/u is raised,then slightly tihgten down the top ones ,that should do it.

thats why i installed the brass thumb rest, my pickups would always come loose from my thumb resting on them, plus also my pickups are not recessed into the body(pictured above) theyre just sitting on top with one screw on each side. thats how primitive it was back then.

Jazzy,
 
I doubt it has much to do with resting your thumb, more likely just due to the fact that there's a lot of vibration going on.
 
If you don't need to adjust them often, you might consider some type of locking compound. For instance, there used to be a non-permanent version of Lock-Tite (not sure about spelling). Or more simply, you could just put a small dab of clear silicone sealer on the threads and that would help a lot (and it cleans up pretty easily).

There is an anti-vibration Loctite product that might be helpful. otherwise, just keep a little screwdriver in your accessories compartment.

Alright. Thanx everybody!
I haven\t got an Alembic (YET!!!!!!!!)
So I couldn\t try out...

hey go to your nearest alembic dealer and pickup your very first guitar,or bass & and  become alembicised!!!!! (believe the the heeeeeyyyyyype!)

Keavin, about your drummer's kit.  Is that stainless steel or what?  How's it sound?

i think its reynolds wrap!. but its actually a chrome looking plastic type of crap.

Wouldn't that be Reynold's Crap?
 
Keavin, I'm following you around the club this morning!
