The thin yet big around body? The fact it's 30+ years old? The adjustable pickup? The neck size? That not many people play one? I have a late 70's Gibson Grabber that I've had for about 5 years now and I have come to realize that it is my absolute favourite bass. I LOVE it. It's old and quirky and has a lot of character. And the tone in unreal. I've done a lot of studio work with it lately and it has been very satisfying. What makes this so?
