Intonation problem : scale length too short after one (reversible) error

[Pipotron3000]

Hi !

My old Jackson Dinky Professional MIJ is mounted with Takeuchi JT580 non LoPro (steel plate it seems) from 1993.
Simply black version Nothing fancy

Trem edges were worn, so i gave them a more curved shape, to avoid grinding again pivot studs (witch were swapped).
It worked right.

BUT as the edges were worn, scale length was already shorter than factory. By around 1mm+. I still could intonate right.

I made a final fatal error : i loosened neck screws with strings attached, to "push" the neck into the pocket.
It worked, i got more sustain ... but i lost scale length AGAIN (something i was not realizing before).
Now some of my saddle blocks are hitting the rear plate ... no more margin

So basically now, i have two options :
Shim the neck pocket to push neck back to it's factory position (simple and cheap)
OR
swap JT580 for another trem

Is it worth it swapping trem on such old and over used guitar ?
Or better push the neck back to it's place and use this guitar to death without swapping anything ?

Frets are in good shape, EM81 working nicely, some buzzing at the locking nut (probably change it soon) ... but this guitar still rocks anyway
Thanks for your help !

Or go for skinnier strings maybe

I’m already in E standard 9-42
Another option is to get higher internal diameter post studs.
To push back trem.

But didn’t seen anyone doing it ...

there are several options. you could take off the studs and anchors and fill the holes and make new ones. Also you could put a shim between the neck and the body.

If you are going to change the trem you would have to know the dimensions of the trem you are going to replace the jt-580 with.

Also 1 option would be to shave some material from the saddles.

I would probably replace the trem. I would not expect a "reshaped" knife edge to hold up over time or be particularly stable with regards to tuning.

93 should have a schaller, pretty sure they started using the 580 in 94. I guess it might depend on what dinky professional you have? Like MH said, just change the bridge

[Pipotron3000]

i checked : it is written Takeuchi.
I will probably buy a new trem, with inserts and nut (to start from scratch ).

I may find some good one, second hand ... without busted out knifes edges

thanks all for you help !

I look at 580's, you might as well just get a FRT1000. Your nut height will probably be wrong on most any new bridge nut combo. So, you can file the nut or shelf on the guitar.

Here is what i found (second hand) :

Witch are obviously (for you ) incompatible at drop in ?
Are the two FR 1000 better than second hand solutions ?

I left FR Special, because ppl report bad plate durability ... so bad knifes edges (again)

I would rather spend an extra 50-60 on a newer FRT1000 than an older bridge( 580) that probably has problems or likely to get them soon. Should be a straight drop in, the gotoh floyds are not, they rub the edges of the route.

Added; the schallers would be drop in too. That's what came on most 93 professionals

Thanks !
I'm a noob about FR

So basically i'm left with this Schaller 100 bucks
https://www.leboncoin.fr/instruments...1980264434.htm

https://www.zikinf.com/annonces/annonce-2016367

I always go for the most cost effective I wouldn't get a special though, but I've had one and didn't really have any problems with it. Generally when you buy a guitar with cheaper hardware the guitar itself is cheaper, so you really can't just blame the hardware.

That 135 schaller might be a good option but you can get a New one for almost same money.
