@, Tune it to drop A (A, E, A, D, F#, B ) or drop A# (A#, F, A#, D#, G, C). Play it like that for a bit then tune it back to standard. If the strings don't feel like they're gonna snap, then you're good. If they do however, tune it to a full step up from the tuning you were checking, then slowly tune it up by a half step every hour or so until you're back in standard. That's the best way to check.
