Re: Do pickups have a break in period ?
In the case of electric guitar components, it's hocus pocus. Amp components deal with much-much-much higher levels of current and voltage, higher by several orders of magnitude, enough to blow the tip off a screwdriver (as those who've tried to do a shortcut on draining the caps have found out), so amp components will definitely change and even break down. Pickups don't "break in", at least not over a period of weeks or months. More like decades as someone said, unless exposed to strong magnetic fields that would jack around with the pickup magnets.
In my opinion it is extremely possible that you're right!
The phenomena of electrical components and wiring "breaking or wearing in" has been observed and commented on for decades.
It is generally acknowledged that speaker cables, and electronic components such as tubes and capacitors benefit from a period of settling in to an electrical current running through them.
It is not uncommon to hear the expression "buring in" related to a new set of capacitors in an amplifier. In the world of high end audio, CD players, amplifiers and tuners are said to sound less harsh and smoother after a burning in period.
Some suggest that it's all hocus pocus, (love that term) others say it's true.
I fall into the later category and think that most if not all electronic components, pickups included, can benefit from a wearing in period.
