Bill Lawrence L500R Humbucker Electric Guitar Pickup Zebra

I received a defective microphonic pickup, the seller sent me a replacement, the replacement was also microphonic, this seems to be a problem with Bill Lawrence USA, same thing happened twice with L500XL pickup as well, 4 out of 4 were microphonic feedback machines, the seller has gone out of their way to make it right but these BL USA pickups are just lacking quality control at the factory
