Check accessories, power supplies, cases and original parts

Confirm exactly what is included in the sale. Some accessories are inexpensive, while others materially affect value or whether the gear can be used immediately.

Where relevant, check for:

• the correct power supply;
• case or gig bag;
• dedicated footswitches or controllers;
• adapters or breakout cables;
• manuals and documentation;
• original parts replaced during modifications.

Do not assume that everything visible in a photograph is included. Have the included accessories clearly stated in the listing or conversation.

If something necessary is missing, add the replacement cost to the total purchase budget.
