Re: Action Issue with 540R
I also disassemble the hard ware most times when making stud height adjustments because I do not like to turn the studs with tension on them in fear or damaging the knife edge, something I learned from Rich and his tech page long ago.
The easy way to change the stud height is to actually take the rear trem cover off, pull the whammy bar up to loosen the spring tension and pop the springs off while holding onto the trem, once that is done, flip the guitar back over, carefully take the trem out of the route and set it aside with strings still attached. Make your adjustments and put it back in the same way you took it out. I think for this first time, you need to see how all of this works, mark where the stud is or count the threads showing up top so you can get close when you put it back and check that stud out, see how it locks down and such.
Saying that, and I am all for learning how to do things yourself, taking it to a good tech can turn an "ehh" guitar into one of your favorites.
