Yes, might, since there's a crack as well.

Hi Hugo,
Looks like a blob of grease, but it could be a dented cable also. Sharp eye!

It's been quite a while since I've seen a bad one, but why not. Especially since they are even older now.

Ok thanks for the advice guys.

When I compared the new pickup to the old pickup I noticed that 2 out of the 3 white pots at the back were differently arranged.

I read on another thread here that these are factory set and should not be altered.. so I did not alter them.

However I dont have access to an oscilloscope, ive been after one for a number of months but to no avail..

Would it work if I adjust these two white pots to look the same as the old pickup?

Will the squeal eventually destroy the laser with use, or is it just annoying but harmless?

Many thanks for your advice to this pickup newb, your very kind

Hi chaoticjelly,
Those controls are for laser power and offsets. I really don't want you to touch them, "no good will come of this" as my wife says. The gain controls should be on the PCB. The gains are switchable electronically and are higher in search mode. The controls will change the play mode gain. You need an oscilloscope do do anything constructive.

Less damage will result if you leave them alone. But this is one reason a good technician costs more, but is cheaper to use in the long run, sometimes in the short run too!
