Double Bass Is it safe?

[AMUNC]

I am changing from spiro's to wound guts, so I am going to use my adjusters to raise my action. Whenever I've changed strings previously, I've always done one at a time to avoid a moving bridge, or a soundpost disaster.

My question is how should I go about moving my adjusters? Should I leave a string on? Should I keep some kind of pressure in the top so the sound post stays in place?
Thanks,
Adam

Ps. I have no problem putting the bridge back in its place, I'm mainly worried about my sound post falling.

I would leave at least a string or two in place to keep the sound post from falling.

Put your new strings on. If you want to raise them and you want to loosen them by a half or a whole step,you can tune them down a half step or so first. i don't. I usually just adjust and then retune. You'll get the best feel for where you want them by trying them at one height, then raising both a half turn at a time until they're where you like them. As always, YMMV.
