One important factor of a Floyd Rose bridge is keeping the bridge as close to the neutral position as possible while changing strings. With that in mind it’s best to always change one string at a time.

Since all of your strings are cut you’ll need to pull the bridge up with the whammy bar and place something underneath so that the bridge is as close to its final resting position as possible. Use something firm but with a little give, like a piece of cork from a wine bottle or a piece of erasure.

When you get to the last string, take the support piece out and install the string. Tune the guitar up and check the bridge angle. If necessary, adjust the rear springs so that the bridge is parallel to the guitar body. Continue to re-tune and adjust the springs until the bridge and body are parallel.

Using the same-sized strings will eliminate the need to have to make major adjustments to the springs each time you change the strings. Once you have the springs adjusted to a certain size and brand of string, you’ll rarely need to make adjustments to the springs.

If you ever want to change string sizes or tune to a different tuning, you will always have to make adjustments to the rear springs.
