Specify exactly what is included in the price

If the photos show cases, stands, cables, pedals, power supplies or other objects, specify which ones form part of the sale.

You can use a simple list:

Included

• instrument;
• case;
• power supply;
• original parts.

Not included

• stand used for the photo;
• test cables;
• other visible instruments.

This prevents the buyer from interpreting a photograph as an implicit promise that everything shown will be included.
