Simple mod to roll off the treble on my Epi archtop?

More importantly, how would I fix that? Given that the bridge has lowered itself quite a bit since the guitar was new (and I've had to adjust it to compensate), that's certainly plausible.

First check for a binding saddle. That is an easy DIY thing to fix.

Next check that the saddle bottom is flat. Again another simple DIY fix.

Next check for a saddle slot that is not flat (possibly due to the bridge top warping). I would put a straight edge on the bottom of top part of the bridge first. Then if you are suspicious that the saddle slot bottom is not flat, it gets a bit tougher to diagnose and fix. Maybe a repair tech is the right way to go.

I removed the saddle. It seemed to be very tight (a good sign, in the context of this discussion), almost as if it had been glued in. Once I got it out, I saw that it was apparently poly that was holding it in place, or whatever was used to seal this guitar (very disturbing!).
I sanded the sides with 600 grit sandpaper, then flattened the bottom, though that didn't seem like an issue, in this case. But I figured it couldn't hurt.
Reinstalled the saddle, and it was nice and loose, just like I assumed it should be.
Not a heck of a lot of difference. So it seems the low hanging fruit was not the answer.
