After purchase: initial maintenance and setup without losing the history

After completing the checks and resolving any purchase-related questions, you can move on to initial maintenance.

Depending on the gear, this may include:

• cleaning;
• new strings and setup;
• replacing batteries or consumables;
• backing up presets;
• software updates that are genuinely needed;
• professional inspection for equipment requiring specialist knowledge.

Before changing configurations, firmware or components, save anything that may be useful for reconstructing the original state.

For expensive, vintage or unusual gear, consider interventions carefully: maintenance and modification are not the same thing and can affect future value differently.
