Howdy all - newbie (to forums and Bass) here. My wonderful wife bought me a bass for xmas after I expressed some interest. It is used and in pretty good shape, although I can't figure out what model it may be. The only info on the back of the head stock is what I assume is the serial number: A09100694. It kinda looks like an Edge 4, but with passive pickups. Thanks for any help and input.
