I'm curious; why would you post pictures of a different amp, in worse condition than the actual amp you are selling, when you have pictures of the actual amp that is for sale?
"THE AMP PICTURED IS NOT THE ACTUAL AMP. THE AMP IS IN MUCH BETTER CONDITION. I WILL UPLOAD PICTURES FOR ANYONE INTERESTED"
Why don't you go ahead and remove the pics currently in your ad, then upload pictures of the actual item for sale?
