One last thing only buy gold plated connectors or you will develop a hum when the tin connections gets tarnished.
@5windowcoupe Tin and gold share a property which is they boh are resistant to corrosion! This is why tin is often used in connectors and the like. If your tin connections are getting corroded, you've got some kind of chemical involved that is responsible or the connectors are so worn that the copper beneath has been exposed. Tin is often preferable to gold since it is so much harder and therefore harder to wear off when the connector is plugged in and out.
