I would not trust strap locks on such manuvers, actually. I would only trust a washer inserted between the strap and strap pin securely held in place by a too screw way too large to be healthy for the bass. In other words, I like even my Fender far too much to screw around with it like that. In one of the vids, it was a broken strap that sent the bass out of its orbit around the player. Victor is well off enough to buy as many basses as he wants, and damn good enough with one in hand to where I got zip to say anything about what he does with one (I usually have enough trouble just keeping my mouth closed watching him play). So I will pull the Thumper Rule on further comment.
