If you want to "hardtail" your jag-stang or mustang, it usually involves physically altering or blocking the mechanisms under the plate. While these mods aren't too invasive, you don't have the option to reverse it without modifying it back to normal.
I have a method that, in my experience, works consistently, and doesn't require any mods.
This only works if your goal is to achieve a non-vibrato jag-stang(or mustang). There is a whole different technique to keep it in tune mod-free for vibrato. Unfortunately, due to the design of this vibrato, the bridge rocking makes it very hard to get the vibrato stable(although you can get it PRETTY good). This non-vibrato method is more stable. Try it out and let me know in this thread if it worked for you!
As we all know, if you tune to pitch on a jag-stang or mustang, and try to play it like a tele, the minute you start doing heavy bending, it goes out of tune. Then you wind up chasing your tail re-tuning and re-tuning. this is why I think most people just block the bridge and forget about it.
The reason for the tail chasing is, the springs are continually trying to reach an equilibrium with the strings, and when you correct one, it throws three others out of whack.
The solution is what I call the "cigar tug" method. The idea is to create equilibrium between the strings and springs and stabilize it by putting maximum tension on the spring by "tugging" it as sharp as it can, all the while making micro-adjustments to the tuning pegs. If all goes to plan, it stays very stable even during aggressive bends, and even if a bend throws it out of tune, just "tug" the cigar, and it'll immediately throw it back into tune! It really works!
1. tune to pitch.
2. Start on the high E, and pluck.
3.grab the cigar tailpiece with four fingers

4. give it a nice firm "tug tug tug" sharp, down towards the butt.
5. tune the high E
6.tug tug again
7.keep tuning until the E is perfectly in tune AFTER the tug.
8. repeat this process up and down on all the strings. It may take a while, as long as half an hour, to finish.
you know you're done when all six strings are perfectly in tune *after* a firm "tug tug tug."
Once you resume playing, you'll notice the guitar stays in tune even when bending strings. You'll also notice that, in extreme bending and crazy stuff, if you just "tug tug" the cigar, it throws everything back into tune.
I hope this works for everyone as much as it has for me. Give it a shot and let me know how it goes!
