My Takamine G series has a saddle like this:
I'd like to lower the bridge action a bit and was wondering:
1. What are the notches on the underside for?
2. Can I just sand down the bottom as one would with a smooth saddle or do I need to use a different approach?
The saddle and nut on theis guitar aren't great and will be upgraded at some point but I'd like to try adjusting the action on this one first as I've never done it before.
