Sometimes issues do arise in transit and can be caused by rough handling, old/brittle wiring, or a component failing under the rigors of shipping. Major issues are covered by insurance - that's why every package ships fully insured.
Many issues are minor and fall under normal user maintenance. These are things any buyer of used electronics should be comfortable handling:
Pots can be scratchy or develop a flat spot from use. DeoxIT solves most of these.
Switches occasionally need to be cleaned or adjusted to make better contact.
