No saddle height left and bridge profiling
Question:
- It seems many people have issues with low to no saddle left for adjustment.
This is what I have been told when I asked a very reliable source, Larrivee has used a thicker than normal bridge to allow the user to adjust the set up to their liking via a bridge profile. When I asked what a profile was I was told that the bridge material is removed to allow for more saddle height so the the saddle can now be lowered again. It just seems that shaving bridge material with the bridge on the guitar is a bit aggressive.
- If someone can explain bridge profiling and how it is done that would be great.
