And now we've heard both sides of the argument we can draw some better conclusions. You can see on the eBay listing that there is no mention of 'custom' at all, nor are there any images of the decal. It appears thebuyer has made assumptions upon this and posted on here with these assumptions.
So on these facts, the buyer did not buy it on the grounds that it was a custom shop bass, and thus no deceit has taken place in my eyes. Of course I cannot see any personal emails or eBay messages between the 2 of them .
