Use photographs as a verification tool
Photographs are not only there to make the gear look attractive. They should help you verify details that matter to the purchase.
Look for images of:
- front and rear;
- areas subject to wear;
- serial numbers or labels where appropriate;
- connections and panels;
- disclosed defects;
- included accessories.
If all images are distant, heavily edited or consistently avoid important areas, ask for additional photos.
A specific request works best: “could you photograph the back of the headstock, the first few frets and the bridge?” is more useful than “send more photos”.
