I've seen similar basses that are also made in Czech republic, but they all have said "Edge European Custom Series" or something of the sort instead of just "Edge Series" like mine does. I'm not trying to find out how much it is worth to sell it, just curious about where it came from so I can tell my son the story when I pass it to him when he comes of age. I consider myself pretty Google-savvy, and I've spent many hours going over searches and websites to no avail. My Landlord has a huge book he calls the Bible of Guitars, and it wasn't in there either. Just ones that are 'very' close, but they are different in one or two minor ways, such as what the back of the neck says or a type of wood used on the neck.
