I am collecting info on pattern variations to try and accommodate all versions of the Fender Jazz (4 string) and hopefully the Lakland Jazz. As ironic as it is - The Jazz I own has no guard! There seems to be three screw patterns? The Lakland Jazz basses look (to the casual eye) to match the one with a screw over the neck pickup but to one side (neckward). Are Laklands their own thing or do they conform to Fender dimensions? That is with regard to 4 strings, not even trying to sort out 5 stringers yet.... If any of you builders/ repairers have some old guards you want to sell off PM me! I don't need pretty ones, just ones that are actual Fender /Lakland dimensions.
