Thumb pick on a bass ?

[epitreture]

I must admit I've never seen a bass player use a thumb pick before.

A few years back I played a few gigs when I was pretty sick, and the prescription meds made me physically weak. I used a thumb pick for those gigs. Was easier to grip the pick in my weakened state.

I seen Sting use the nail on his right thumb as a pick.
