Saw this bass on fleabay a while back. I'll tell you a neat trick, as the pickup is microphonic, plug it into an amp and speak into the pickup, it's basically a microphone. Also run it through an overdrive or fuzz, sounds awesome!
It's an early 70s bass, you can tell by the headstock, if it's wooden it's early to mid 70s, if it's painted black it's late 70s to early 80s. They were mass produced and sold at the mighty Woolworths, back in the day.
