Hi friends, this is my first post here, I'm Anibal from Spain, proud owner of an American Vintage '62 Jaguar. Firstly I want to congratulate you guys for such a great forum, I've been a while reading the threads and watching the nice guitars in there 😀 Secondly I would like to apologize if my english is not good enough.
I love the sound of my guitar and I have no particular issues with the bridge, I use the stock one (with 11 strings) and I have no problem with the adjustment. But the tremolo-tailpiece system confuses me a lot.
The way it's adjusted now, the tailpiece is a bit low and I have problems using the tremolo: The tailpiece is so low that the low E string is literally touching the screw just below the string, (you know those 3 big screws in front of the tailpiece). And when I use the tremolo (I use it a lot in a very subtle way) there's an awful scratch from the wound E string against the screw back and forth, and that horrible sound is amplified when it's plugged in. I also think that the string is suffering with the scratch and I'm afraid of breaking the string.
I've been loosening screws up and down but I can't raise the tailpiece, and I wasn't able to move it, so I would like to know how to fix this problem. Here's a picture of the string against the screw:

Thanks for the helping, greetings!
