When you start playing the violin the first finger pattern you usually learn is a pattern where there is:
a whole step (a major second) from open string to the first finger,
a whole step from first finger to second finger,
a half step (a minor second) from second finger to third finger,
and if you include the fourth finger a whole step from third to fourth ...
The problem is my Jaguar has a 7.25 in radius and the Mustang is 9.5in...I settle mine with graphtech saddle and problem solved...I just don’t like the look of the Mastery, too high-tech for a vintage thin line Jaguar...Cheers
