So, I learned an interesting tidbit today about a piece of gear that I bought as a "blem" from an online retailer (and no, it probably isn't the retailer that you are thinking of). I have a multieffects box that I bought in February and one of the knobs stopped working correctly this week. So, I called the manufacturer since the unit is still under warranty. Well, the support person asks about who I am and then asks, "Did you buy this new?" He goes on to tell me that this unit was in for repair last November. He didn't know what was repaired, but apparently it was sold, repaired and returned. The unit was then sold to me. Guess now I have some insight on the origin of "blems."
