I am starting to get more serious about playing my "beginner" bass. I bought it from a kid off of eBay. Is this a Legend and, if so, is there any way to determine the exact model and approximate year of manufacture? It has EMG-SSDs. Not sure if the black knobs are original and they don't match the machine heads. The bridge is silver. I can add a better shot of the front of the body if necessary. Thanks.
