So I have been doing a little research and seem to be going down a rabbit hole. I wanted to change a TOM bridge on a Jackson with a 12-16" radius however I cant seem to find one with the same radius or one that will work, would a "normal" TOM bridge work or would I find a difference in the feel.
Has anybody any information or had experience in this ?

Tune O Matics are classically radius'd to 12" to match the standard Gibson radius.

Some companies may offer a 16" radius TOM, but I'm not up to date with that as it's not something that comes up.

You may need to just buy a 12" one and file the inner 4 saddles so that strings sit in the correct 16" radius to match your board.

Not a Rocka thread? :scratch:

Typically, you want the bridge radius to match the radius at the headstock end of the fretboard, not the other way around.

Not on a compound radius fingerboard, though: the radius at the nut will be different that the radius at the bridge.

Keep in mind that past the last fret on a compound radius, the radius should continue to flatten. So like on a 12-16 your bridge should be flatter then 16. Think of your strings on a compound radius as making a cone shape.

ITT Donnie dropping the math. Came here to say that. if you're at 12" at the headstock, and 16 at the 24th, the radius at the bridge would be ~17.3". A 16" Tom is probably gonna be as close as you get.

This is correct.

I recall that the Schaller TOM bridges are 14" radius, but I could be misremembering. Either way, the difference is going to be miniscule. Trying to put a TOM on a vintage-ish Fender with a 9.5" radius would be a lot more noticeable.

Both the gts and gtm bridges are 12" by default. I'd not be surprised to find they are or were available in 14".

Edit: yarp you are correct

Except in practice it is typically what I said. Most TOM bridges are 12" radius. A Floyd Rose is 12" radius.

FLOYD SELLS SHIMS FOR THIS PURPOSE GODDAMNIT

I'm not saying you're wrong, because you aren't, but you should be!

I know, but a) they weren't around for years, and b) hardly anyone uses them, including manufacturers. And really, no one ever really notices if they're there or not.

I certainly do. I'm super picky with string action.

When I first put together my Warmoth with 10-16 compound and had a Floyd bridge (comes 12" stock) I was super annoyed that I couldn't get low action on middle strings.
Then I discovered shims, and shimmed up the bridge saddles to circa 18" radius... and surprise... I got nearly perfect string action across all the strings!!!

And no... I'm not that kind of person who's like "I can only play 14" radius, otherwise my hand gets cramped booohooo"...
No no... I don't carea about the radius as long as it's 12" or more, since that's from experience the minimal radius to be able to get Rocka (tm) style low action.
And yeah I have a little higher action nowadays than a few years ago but still low.
I can't tell difference from a 14" or 16" or whatever just by playing, maybe because I dont care.
All I care about is that I have as close to my prefered action as possibe.

And not having a radius matched Floyd Rose will fucking DESTROYYYYYYYYY any kind of consistent action across the strings!!!

Apparently it worked! Attention confirmed!

But it's not the point.

The point is that whoever is NOT matching the radius to the fretboard with a Floyd Rose is not picky about setup.
Well, I'm glad for those people.

But those who takes setups seriously MUST shim the saddles to the correct radius, otherwise you caaaaaannnnnn''''''ttttttttttttttt get a even string action across all strings over the frets!
