Reflowing Solder Joints

[Donnie B.]

The 1991 guitar I just bought doesn't have any obvious shorts, opens, or intermittent solder joints but I was wondering if it wouldn't hurt to reflow all the joints just to insure 100% electrical conductivity. Can a solder joint over time turn a bit "cold"?

Should I reflow the joints or leave them alone unless an obvious problem surfaces.

Thanks.

There is absolutely no need to reflow perfectly good solder joints. Ever.
