Yes, it's all Gotoh.
However, if you're having trouble with string breaks at the saddles all you have to do is locate the offending burrs and gently file them smooth - no need to replace anything.
If you don't feel confident in that, or can't see where the problem is, any competent technician should be able to do it in two minutes, very cheap and a lot less hassle than messing aobut with new saddles that may or may not have the same issue.
