Question about saddles on an Edge trem
I just got an Ibanez S540LTD, and the trem (an Edge) was pretty dirty, so I took it off to clean it and change the strings. I took off the saddles, but afterwards I noticed that on the underside of four of the saddles, there was a backing plate of sorts (something to keep those little metal cubes from falling through) and two that had no plate. I assume this is because of the height difference in the saddle positions, but I don't know where to put the two "see-throughs" (the ones with no backing plate). In which positions do they go?
