... there is no one perfect solution for every guitar's tone, as there are too many contributing factors.
This, big time!
I involuntarily chuckle to myself every time I hear or read someone opining that bone saddle/nut are sonic upgrades to that man-made crud, blah blah. It is exactly as SF stated: there are a myriad of factors that contribute to tone, nut and saddle being just two And even this discounts the fact that
every piece of bone (just like wood) has its
own individual properties that are
not completely predictable.
Then there is the equation of which man-made material: tusq, micarta, graphite, plastic, etc., each having their own properties. Moreover, the "better" the guitar is engineered and built, the
more these materials are considered as a sum of the guitar's overall voice. Which is often why cheap guitars typically benefit from a saddle replacement (or even a
properly cut cheap nut which can sound better than replacing it with another magic material!). It's not like the bone material "fixed" the tone as much as any saddle harder/denser than cheap generic plastic would likely improve its tone; but not axiomatic for pricier guitars whose "whole build" is part of the equation from the get-go.
At the very least, a saddle swap is an inexpensive experiment that is easy to A/B, and reverse if need to. Glad you found out what works and what sounds better!
