A symbol of Mr. Billy Sheehan's followers?

I want Yamaha Attitude (I don't have it).

But I think that it's a symbol of Billy Sheehan's followers too.

Black cat!
I found it at Itoya which is Japanese stationary shop in Takashimaya of Futako-tamagawa and got it!!

It's 180yen. Very cheap.

Watch the Billy's bass carefully.
It's same w/ my cat. maybe...
