i didn't really know where to post this but i guess this will do.
I've noticed Victor Wooten uses a bobble on the head-end of his bass. I was just wondering if anyone knew what it does and how you get one that fits nicely over the head and still quite tight on the neck.
And i've also noticed that his brother Regi uses two really big ones, and wondered how he managed to still get notes out of his guitar.
