The agitaters used for white bass are all kinds of shapes, although the most popular is cylindrical with a square main line end and a rounded leader end. Square front popper style.
My uncle made some years ago by hand on his wood lathe that were shaped like old style buoys and we caught tons of whites using them. If you aren't already as busy as you can handle you might see if you can market them to white bass fishermen. We used to take a five gallon bucket with us, and many times we had to quit because the bucket was full. Most popular trailer bait was a 1/16 oz jig with white maribou or white curly tail. Second most popular was the same in black. Yellow was third.
