Just say no to low G! :shaka:
But, if you really have to try it, it's eaasier to reuse if you have a slotted bridge or a pin bridge. If you have a tie bridge, try to leave the "knot" intact, just pull the string through the loop, then if you want to put it back on, just push the string back through the little loop and reinstall. I usually only reuse strings from a concert to a soprano.
