While tightening bolts on an SD-10, I found 3 in a row that were very loose so I tightened them snugly but I didn't crunch them. When I sat down to start tuning and happened to glance at the three bolts, to my horror I saw that the area of the plate under those bolts was no longer straight, but had dipped lower between 1/8 to 1/4 inch? I really didn't measure it because I immediately loosened those bolts again to approximately the way they were before! What's going on here? Should they be tightened anyway? I know I should jerk that plate out of there and replace the plate supports, but this is a church, I don't think they'll buy it. Should they be left a little more than hand-tight, or what? The bolts are located just forward (toward the keys) of the massive delta shaped plate bracing that supports the back of the plate where the bass bridge is.
