so a man i work with used to play bass back in the 70's. he tells me he still has his bass, and he thinks it's a vox. i can't find "vox" anywhere on it, and i have no idea on how to search for this thing. question #1: what is it? question #2: when was it made? question #3: what would it be worth today? question #4: do i dare try to tune it?
