Replace Floyd Rose on Vintage 1989 Ontario SL1

[charisarvanitis]

Hello fellow forum members, this is my first post here I have been reading for years the forum but only recently registered. I would like to ask the experts here about some tech work that I am considering. I have a in mind a 1989 Jackson Ontario SL1 which comes with the Jackson-stamped JT590 Tremolo - do you think is worth replacing with a new OFR in terms of tuning stability and trem quality, and if yes, will it need additional routing/luthier work to fit or is it an easy swap? Thank you for your time and apologies if that topic has been covered again in the past

If there is a problem with JT590 then replace it with Schaller trem: https://schaller.info/en/tremolos/359/schaller-tremolo .Usually biggest problem is JT590s base plate which has no steel inserts for intonation bolts.

I don´t think OFR is that much better that it is worth of routing work, which it will probably need.

stick with the schaller trem (same thing as jt590)...it works just as well as a floyd...i had a schaller trem on an old charvel for 15+ years, never gave me an issue...d.m.

The OFR is an easy swap. But if your Soloist has a recessed cavity, the long poles may limit pull-up.
If you have a small sanding drill (like a dremel or your wife's self-care nail gun), you can do it yourself.

If there's nothing wrong with the Schaller JT590 then why replace it? If it needs replaced I'd go back with a Schaller because if it's recessed the route for the JT590 is shorter than an OFR route.
