The Bill Lawrence pickups I got had the tubing around the screws instead of springs. You sometimes have to cut it depending on the pickup ring and string height. You can just crush the hell out of it, but I got a bad feeling about that when I was messing with it. Sharp scissors, snip snip, and that was the end of that.
always use tubing in place of the springs, i think fender did this at one point, maybe still do on american models. the springs can become microphonic and nobody wants that. lawrence pickups come with tubing and duncan's fender style pups do to, yet they still use springs for humbuckers, strange.
