A pickup is rated in millivolts. That means a thousandth of a volt, so the copper wouldn't break down under that small of a voltage. Also the amplifier does not power the pickups, the amplifier only amplifies the voltage that a pickup creates.I've always wondered this too, because I feel like current running through the copper wire may do something to it over time - don't speakers use copper coils too? I know for sure they have a break in period, but it may have more to do with the speaker cone itself, and if the copper is affected, it also has a great deal more current running through it...
Just a thought though. That being said, I haven't really noticed any of my pickups 'breaking in' so to speak.

Try your other guitars, do they sound the same now?I've been playing my Gibson 57 LPC all month since i installed these pickups and have'nt even touched my other guitars.
Would a pickup need a break in process? I swear i have a set of 59's that has slightly changed in tone since i installed and played them now for about a month.
+1 Have noticed that! and also don't expose your pickups to extreme heat or electromagnetic currents. This will definetelymore likely to be that its winter now. temprature and humidity change the way soundwaves travel thru the air, among other things
