I have a bass that was defretted that cannot achieve a low action because the bridge saddles won't go low enough. I know that shimming the neck tends to be a solution to this, but would sanding down the bottoms of the saddles of the bridge, or even sanding the entire bridge base down, also be a viable option? The bass is an early 90s Ibanez SR895 with a Fender-esque bridge and saddles for what it's worth.
