Hi Guys,
When having my lefty Epic's switched over to right hand stringing, they only had to cut new saddles for the bridge. Whether or not the slots would be in the right position (when switching from lefty to righty, or righty to lefty), may or may not be an issue. Ordering new 'uncut' saddles and cutting them yourself might be your best bet.
Just my experience. Hope this helps.
Regards,
Kimberly
