Help! Changing strings on a jp50

[Viter]

So i've decided that i want some new strings on my jp50, but i never changed strings on a floating bridge before, and I'm so confused, i hear different things from everybody.
If anybody please could explain me, or upload a video of them changing strings on their john petrucci guitar, would help me alot!

You can either A: Change them one at a time or B: Block off the bridge by putting something under it.

But when i detune one of the strings the others are gonna change as well? so how can i do 1 at a time?

Viter, it's really not that hard, just time consumming.

1. Be sure the guitar is in tune (with old strings still on).
2. Remove the high "e" string. Then put new E string on (stretch it out thoroughly!!!!!!!!!) and once the new string is on and in tune THE REST OF THE GUITAR SHOULD ALSO BE.
3. Then do the same with the "B" string and so on.
* the springs should not play a major roll in this if you STRTCH OUT THE NEW STRINGS THOROUGHLY!!)
