Pickups and electronics: check consistency, soldering and replacements

Pickups, potentiometers, capacitors, switches and wiring can provide many clues. Compare codes, materials, wire colours, soldering style and layout with documented examples.

A disturbed solder joint may indicate service or replacement, but it does not by itself explain when or why. Conversely, old-looking solder does not automatically authenticate a component.

Record which parts are consistent, which are known replacements and which cannot be verified without invasive work.

Avoid desoldering components merely to “check more closely” when the operation could destroy useful historical evidence.
