Ahhh that kind. I have that kinda bridge too. Pretty simple really.
Put the string in from the back, pull it all the way through the body. Make sure the ball end is stuck in the body. Then pull the loose end towards the nut. Put the end through the tuning machine's hole and check that the string is resting in the correct bridge and nut slot. then hold down the string at the nut and just before the tuning machine, and use a peg winder to twist (while holding down the strings). They should turn nicely, and the loose end can be cut off once the tension of the string is settled. Well. Easier to show then to write .
That's actually very easy if you know how to block the trem. You can change all the strings within 20 minutes and have the trem back in perfect floating angle.
go thru the bridge hole, thru the tuner hole, turn away from ur body until 2 semitones away from standard. Bend at 12th fret and retune until 1 semitone, then again until standard. Then bend until the string "stabilizes" near standard pitch after bending. done.
Go to www.jemsite.com and find out for yourself. The best way to learn is self learning.
The first time you do it, you'll prob take a couple hours. Just rememeber to make yourself a trem block.
Btw, stringing the ball end at the head of the guitar is really ok to do and it makes the guitar safer and prevents the string ends from cutting up your case.
It's just something that blocks the trem from moving. Can be anything from batteries to a piece of wood etc. Open the backplate and insert it between the trem and the body of the guitar. It should hold and stop your bridge from moving while you restring.
