Here's the deal - I bought my first real bass, an Epiphone Goth Thunderbird IV, for $250 last week from a local store. My first bass was a Vinci I bought off Ebay a few years ago and never really got into it. Well now I am picking it back up and trying to learn. OK back to topic, I was extremely excited about the purchase and checked the kneck, frets, and finish as best as I could. It was not advertised as used so I felt like I was getting a decent deal. Well I discovered the other night that the real serial number had 3 digits removed and then upon closer inspection noticed "used" barely visible on the back of the headstock. I haven't gone back to the store yet, but I am first thing Saturday. What do you think I should do? I was thinking about getting my money back just based on principle.
