POSITIVE INFORMATION ALERT!!!
I had NO idea about this until I was looking at my Jackson RR24.
Probably I've been completely ignorant of this fact for all years, but it makes bridge swapping on many guitars SUPER EASY! I thought FRT-2000 had completely different threading...
I know FR Special and most licensed stuff have the wrong threads, but this is great for everybody who's found a nice Jackson Pro/ESP LTD-1000/whatever that comes with FRT-2000, and likes the guitar a lot, but find the bridge a bit wonky (which is why I replaced it on my RR24)
I have occasioanlly googled this and I've never seen any forum threads or information pages verify this but, now I can verify it for you!
If somebody has a FRT-2000 with other threads, please share what guitar and year it is, because it might be different from different eras, maybe!
Here's my RR24 with the new Schaller Lockmeister bridge! It works much better than the FRT-2000, but I still have to find the right action, and stuff... But it also needs a complete refret, so maybe I'll leave this as it is for a while.
Refrettings shoud be done during winter, so you dont have to worry about sharp fret ends when it gets cold after summer
