Tone Matters. Use It Well.
I think the things you can only really screw up are knowing what direction to turn the truss rod for increasing/decreasing the neck relief. Also, what direction adjustable saddle screws turn to lengthen/shorten the relative string length. Some adjustable bridges work counter-intuitive to the direction you might think they're supposed to be.There are tons of videos and explanations. The key things to remember are small increments and go slow. The first time you do it is definitely nerve-wracking. The first time a neck creaks definitely tests your bladder strength. But unless you have an unusual situation (like a frozen truss rod) or do something really stupid, anything you do is reversible.
Adjusting the tremolo spring claw tension should prove interesting if increasing/decreasing my string gauge...also, I've not yet tried adjusting saddle height on a tremolo guitar yet, so this will be a new adventure in shoulda/woulda/coulda.
