Here is my E7 for comparison. Note the location of the bridge/trem pivot screws on this model compared to the E9. My E strings pass right over the pivot screws, they are not in the corners of the bridge plate like on the E9. However, the E9 arrangement is probably better for function and longevity. The E7 setup uses only the small wood screw shown at right in the 3rd photo, which has a rounded groove just below the head for the plate to pivot in. The lateral string loading on these screws enlarges the holes in the body, an issue I will soon address on this guitar. If anyone has the Fender/Squier specs for setting up this early type of trem, please post them here. Everybody with these guitars seems to deck the trem and use it as a hardtail.
