Iíve recently bought a telecaster and Lately Iíve been curious to know if it has the original puís or if these have been changed. Is there anyway to determine the year of production of the pickups without unsoldering them or is that the only way to check this out?
A local guitar shop offers the service as I donít have an ohm meter, but charges 150$ for such a checkup, so if thereís anyway I can check myself any info would be greatly appreciated.

Best regards
