I have an old Lotus L760 neck-through bass that I'm wrestling with. Small washers under the truss rod nut got the neck very straight, and the nut is slotted right. But the action is still crazy high. I sourced this bridge on eBay, assuming it was the original stock. It dropped in fine. But the chunky saddles are a good 3/8 inch thick and even fully lowered don't allow for reasonable action. Do you think there were different thicknesses of these saddles back in the early 80s? Again, it's neck-through, so no shimming possible here. I could recess the bridge, but I'm hoping there's another answer.
